275304 - Using the mouse wheel un-hovers any hovered element

Status: RESOLVED FIXED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Josh Lee]

I have a large element on my page that changes appearance on hover, but I
noticed that it "flickers" when you mouse wheel over it. This behavior does not
occur when scrolling with the keyboard.

1. Move the mouse over the green div to turn it orange.
2. Roll the mouse wheel. The div turns back to green.
3. The div turns orange when you move the mouse.
4. It works fine with the keyboard.

Testcase to follow.

I'm running:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041007 Debian/1.7.3-5

and they both show the bug.

Oh wait, I just downloaded the latest nightly Mozilla/5.0 (X11; U; Linux i686;
en-US; rv:1.8a6) Gecko/20041220 Firefox/1.0+ and it appears to be fixed.

Basically a duplicate of bug 78765, except not fixed until bug 20022 landed, for
some reason.
