865563 - Scrolling over URL bar's drop-down menu triggers bounce behaviors on page below

Status: RESOLVED DUPLICATE of bug 861669

(Core :: Widget: Cocoa, defect)

Description

[David Corry]

With browser.snapshots.limit set to enable the bounce at the edge of a page, if you open the URL bar's drop-down menu by typing (or by the arrow) and scroll over it, it triggers the bounce effect on the page beneath it.

When I set browser.urlbar.maxRichResults to something high enough to cause the menu to have a scrollbar, it scrolls normally, but still causes the same effect at the top and bottom of the menu. It seems like the menu is trying to bounce, but the event gets passed to the page instead.

Although hard to tell, this bug is actually a duplicate of bug 861669. The detection of the scroll target implemented in bug 673875 is not sufficient and causes unexpected scrolls in various scenarios.

Makes sense (especially with the bug 861669's summary change) - I'll dupe it.
