1665973 - Blank bottom space when page becomes non scrollable

Status: RESOLVED DUPLICATE of bug 1740289

(GeckoView :: General, defect, P2)

I noticed this on Twitter first, clicking on "share" makes the page non scrollable which makes us not paint where the URL bar should be, except if the url bar is hidden the app doesn't know that it has to show the URL bar so we show an empty space.

STR:
With the attached test case:

• scroll up to hide the URL bar
• click on "toggle scrolling"
• Notice empty space at the bottom

This is the current behavior.

I guess we don't necessarily have to notify the app to fix this bug.

I can't reproduce this bug in Fenix 100 because the toolbar opens when I tap the test case's "Toggle scrolling" button. So I don't really know if the original problem is still happening or not.

I see that same toolbar behavior for the STR in bug 1694607.

Yep, it's been fixed by bug 1740289. When the root content becomes non-scrollable, now Gecko notifies it so if GeckoView apps can handle the notification properly, the toolbar gets visible.

Moving toolbar bugs to the new GeckoView::Toolbar component.
