294910 - the drop-down box in a <select> tag isn't treated as a child of the tag's parents wrt :hover

Status: UNCONFIRMED

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

Description

[Jon Dowland]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050421 Firefox/1.0.3 (Debian package 1.0.3-2)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050421 Firefox/1.0.3 (Debian package 1.0.3-2)

When you activate a <select> tag, the drop-down box is not treated as a child
element of the tag or of it's parent, with respect to the parent. So, if you
apply CSS style to a parent element using :hover, it does not take effect when
focus is on the drop-down. The test case is an extreme example where :hover is
necessary for the element to be visible. Thus, this behaviour renders the
drop-down useless.

Reproducible: Always

Steps to Reproduce:
1. hover over the h3.
2. keeping within the boundaries of the div (marked 1px border), select the drop
down. A double-click may be necessary (see bug 163503).
3. move the mouse carefully over the drop-down

Actual Results:  
the drop-down disappears, as the :hover condition isn't satisfied and thus the
style reverts to display: none

Expected Results:  
The :hover condition should still be met, so the div and select, drop-down and
all, should remain.

Attachment: test-case as described

Here's a copy of that test case incase my site disappears.

Fails with Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8)

(for sake of comparison, works in konqueror/safari, fails more fundamentally in
the IEs I've tried)

Works for me: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2)
Gecko/20050520 Firefox/1.0+
but
fails: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.5) Gecko/20041110
Firefox/1.0

(so maybe this was purposely fixed between those revisions in win32-specific code?)

WFM - Windows XP/Firefox 1.0.6 (perhaps this only affects other ports?)

I can reproduce the problem in Firefox 20070614 trunk on Linux.
