Some WPT tests (when executed with the WPT runner via WebDriver) open new browser windows via JavaScript invoking window.open(...) and then run the test on this new window. And there are issues when the test itself calls document.elementFromPoint() on some coordinates that are ourside of the window size. MiniBrowser its opening new windows by default with a size of 100x100, which its too small and causes failures For example on the WPT test: css/css-flexbox/hittest-overlapping-relative.html

I think it makes sense to do it in any case. Just try a basic example of window.open with the minibrowser and check how bad it looks the new window it opens: (you almost can't see it).

The spec says 100 is the minimum but not the default, so we can change that behavior and use a different default size, for example parent window size.

Its there a spec for this minimum/default size? I can't find any reference at https://html.spec.whatwg.org/multipage/window-object.html#dom-open What Firefox and Chrome seem to do its to open new windows without a specific size on new tabs.
I saw it in https://www.w3schools.com/jsref/met_win_open.asp also included in https://developer.mozilla.org/en-US/docs/Web/API/Window/open#Window_features
Created attachment 396003 [details] Patch v2: set the default requested window size to the one of the old window
Comment on attachment 396003 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=396003&action=review > Source/WebCore/ChangeLog:11 > + The size of the new window its not specified, and we were defaulting is not specified > Source/WebCore/ChangeLog:12 > + to the minimum of 100x100 which its just too small for some tests which is > Source/WebCore/loader/FrameLoader.cpp:-4133 > - // Zero width and height mean using default size, not minumum one. So, WebCore is indeed doing the right thing here, if not size is specified the default one is used. We are failing to provide a default size when windowRect is called before the window is shown. We can fix it in GLib UI client doing something like this in windowFrame(): GdkRectangle geometry = { 0, 0, 0, 0 }; GtkWidget* window = gtk_widget_get_toplevel(GTK_WIDGET(m_webView)); if (WebCore::widgetIsOnscreenToplevelWindow(window) && gtk_widget_get_visible(window)) { gtk_window_get_position(GTK_WINDOW(window), &geometry.x, &geometry.y); gtk_window_get_size(GTK_WINDOW(window), &geometry.width, &geometry.height); } else { GdkRectangle defaultGeometry; webkit_window_properties_get_geometry(webkit_web_view_get_window_properties(m_webView), &defaultGeometry); if ((!defaultGeometry.width || !defaultGeometry.height) && WebCore::widgetIsOnscreenToplevelWindow(window)) { int defaultWidth, defaultHeight; gtk_window_get_default_size(GTK_WINDOW(window), &defaultWidth, &defaultHeight); if (!defaultGeometry.width && defaultWidth != -1) geometry.width = defaultWidth; if (!defaultGeometry.height && defaultHeight != -1) geometry.height = defaultHeight; } } completionHandler(WebCore::FloatRect(geometry)); Note that we will still get 100x100 when the window doesn't have a default size set (it's not the case of MiniBrowser), but we don't have a way to get the previous window here, so I think we can just assume that apps should handle that case by setting their own minimum size if 100x100 is too small. > Source/WebCore/loader/FrameLoader.cpp:4141 > + else > + windowRect.setWidth(oldWindowRect.width()); This is changing the behavior for other ports, I think we should handle this in WebKit layer, but if we end up doing it here, it should be under plartform ifdefs, or ar least only done when windowRect.width() == 0. > Source/WebCore/loader/FrameLoader.cpp:4145 > + else > + windowRect.setHeight(oldWindowRect.height()); Ditto.

Maybe we can try to do both things? use the default window size if set, and if there is no default window size, then use the size of the previous window. > > Source/WebCore/loader/FrameLoader.cpp:4141 > > + else > > + windowRect.setWidth(oldWindowRect.width()); > > This is changing the behavior for other ports, I think we should handle this > in WebKit layer, but if we end up doing it here, it should be under > plartform ifdefs, or ar least only done when windowRect.width() == 0. > > > Source/WebCore/loader/FrameLoader.cpp:4145 > > + else > > + windowRect.setHeight(oldWindowRect.height()); > > Ditto.

I'm not 100% sure if you can have a view backend without a specified size, but I suspect its not possible. So I guess this its not needed for WPE. > > Tools/TestWebKitAPI/Tests/WebKitGLib/TestUIClient.cpp:370 > > +#if PLATFORM(GTK) > > + if (m_shouldCreateWebViewsInNewWindowsAutomatically) { > > + g_assert_null(m_parentWindow); > > + m_parentWindow = gtk_window_new(GTK_WINDOW_TOPLEVEL); > > + gtk_window_set_default_size(GTK_WINDOW(m_parentWindow), m_DefaultGeometryNewWindows.width, m_DefaultGeometryNewWindows.height); > > + gtk_container_add(GTK_CONTAINER(m_parentWindow), GTK_WIDGET(newWebView)); > > + gtk_widget_show(GTK_WIDGET(newWebView)); > > + gtk_widget_show(m_parentWindow); > > + } > > +#endif > > Maybe we can just change showInWindowAndWaitUntilMapped() to set the default > size, I don't think that will affect other tests. Ok, I see now that we need > it for this particular test. Then I would add a parameter > ShouldSetDefaultSize or something similar. > I tried but I couldn't manage to set a default size from the function showInWindowAndWaitUntilMapped() that webkit_window_properties_get_geometry() would report. As far as I can see the main issue with showInWindowAndWaitUntilMapped() its that its not called on the "create" signal when the webview its created, but its called manually by the test after that. So it works when you care about setting a size for the current test window but it doesn't work for setting an automatic/default size for a new window that opens. For this test to work I need to set the default size of the window when the new webview its created in the signal handler for the "create" signal, so when the signal "ready-to-show" triggers the window already has a default size that webkit_window_properties_get_geometry() can query.
