Tentative fix: Instead of: FloatRect fr = page->chrome()->windowRect(); FloatRect sr = screenAvailableRect(page->mainFrame()->view()); fr.setLocation(sr.location()); FloatRect update = fr; update.move(x, y); We should have: FloatRect fr = page->chrome()->windowRect(); FloatRect sr = screenAvailableRect(page->mainFrame()->view()); x -= fr.x(); y -= fr.y(); FloatRect update = fr; update.move(x, y); That change seems to fix the problem. 1506682 1 yevseytsev 2019-02-15 11:24:53 -0800 Tried to reproduce a bug in Safari and Firefox using the code provided, but windows are not moving at all. As well Firefox is no longer uses WebKit, so I am not sure it is a bug nowadays. 1506756 2 yevseytsev 2019-02-15 13:40:23 -0800 Please ignore the second part of my previous comment, Firefox uses WebKit only on iOS 1509056 3 yevseytsev 2019-02-22 10:48:24 -0800 in webkit/Source/WebCore/page/DOMWindow.cpp file there is a code that prevents window geometry to be changed void DOMWindow::moveTo(float x, float y) const { if (!allowedToChangeWindowGeometry()) return; Page* page = m_frame->page(); FloatRect fr = page->chrome().windowRect(); FloatRect sr = screenAvailableRect(page->mainFrame().view()); fr.setLocation(sr.location()); FloatRect update = fr; update.move(x, y); page->chrome().setWindowRect(adjustWindowRect(*page, update)); } 1892432 4 ahmad.saleem792 2022-08-19 09:33:08 -0700 I am not able to reproduce anything from the test case in Comment 0 and all browsers (Safari 15.6, Safari Technology Preview 151, Chrome Canary 106, Firefox Nightly 105) ignore the "Move Me" input and also don't show anything in console. Link - https://jsfiddle.net/3gowr4c5/ The referencee code in Comment 03, is still present in slightly changed / refactor format: https://github.com/WebKit/WebKit/blob/64f843f962fd4b62b95fb3c3c53127b6f526fbcd/Source/WebCore/page/DOMWindow.cpp#L1758 rniwa@webkit.org - Is something still needed? Thanks! 1892454 5 ap 2022-08-19 10:31:37 -0700 As documented in <https://developer.mozilla.org/en-US/docs/Web/API/Window/moveTo>, Firefox only performs a moveTo if the window was created by window.open(). Looking at allowedToChangeWindowGeometry(), WebKit appears to have a different policy, it blocks moveTo if invoked from a mouse event handler. It also needs to be the main frame, not a subframe. The test needs to be adjusted accordingly to verify if this is still an issue.
