57598 - [CBX]Dropdown menus are not scrolled with wheelmouse

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect, P3)

Description

[Eugene Savitsky]

1. Open the URL
2. Open the OS dropdown
3. Try to scroll it with mouse - it closes instead of scrolling it.

This is bad. I'm fighting with this bug every day - can't remember it does not
work in mozilla... :(

Is this really a dup of bug 50339? 50339 seems to deal w/menus (File, Edit,
etc.) and this one is about <select> boxes...

CC'ing Brian Ryner because he is the owner of bug 50339

you're right, this is not quite a dup.  i'm going to be rewriting a large part
of the xp mousewheel code fairly soon which will fix a whole bunch of bugs --
i'll make sure this case works also.

Reopening and assigning to [e-mail] so it doesn't get lost in the
shuffle...

Completing reassignment... sorry for the SPAM...

Bug 14935 seems related to this. It's assigned to rods and is about form lists
not listening to mouse wheel messages. I cant decide if it's a dupe or not.

Patches work very well for me on Windows, and fix all of the bugs they're 
intended to...

Are you sure this is fixed?  When I drop down a combo box and roll the mouse
wheel, without moving the pointer off the comb box, the drop down list
disappears.  I have to move the pointer to be over the drop down list, not just
the combo box, for mouse wheel to perform as described.

Maybe I'm drumming on a design issue, so here are some good reasons why the drop
down list should scroll without the user having to move to pointer off the combo
box and onto the drop down list:
1) Clicking the combo box puts the keyboard focus onto the drop-down list (up,
down, accelerator keys work).
2) Clicking the combo box indicates that the user desires to work with its contents.
3) MS does it that way :)
