What was the use of those two calls? They disappeared now.

I'd swap updateViewportSize() and drawingAres()->setSize(). updateViewportSize() calls _q_contentViewportChanged() which sets the visiblerect on the drawingArea. There could be some side effect to set the visiblerect, when the size is not yet set properly.

Viewport property change callback is now bundled with TILED_BACKING_STORE. Is it intentional?

WebChromeClient::dispatchViewportPropertiesDidChange() and  WebPage::setViewportSize() are very lookalike now. Wouldn't be better to move the common code to a dedicated function?

True and that might need to be revisited later. Currently a lot of additional code in Grob were due to us calling these (the implicit/explicit). That code were related to fit to width.
