59830 - Mouse wheel while drop-down list is dropped-down causes incorrect behavior

Status: VERIFIED DUPLICATE of bug 14935

(Core :: Layout: Form Controls, defect, P3)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.16-3 i686; en-US; m18) Gecko/20001110
BuildID:    2000111021

If I click on a drop-down list, causing it to drop down, put the cursor in the
dropped-down list and move the mouse wheel, the entire page scrolls, but the
dropped-down list does not.  It detaches from the form element, and just sort of
floats near the mouse.

Truly bizarre looking.


Reproducible: Always
Steps to Reproduce:
1. Visit http://www.mozilla.org/quality/help/bugzilla-helper.html
2. Click on the dropdown list next to Component
3. Move the mouse down slightly, so it is inside the listbox.
4. Move the mouse wheel up or down.


Actual Results:  The page scrolls, but the list stays near the mouse, even when
the element it should be attached to is moved or gone.	

Expected Results:  Either scrolling the contents of the list, rolling up the
dropdown and scrolling the page, or scrolling the page leaving the dropdown
attached to its list.

I see this too, with just about any dropdown box.
It's related to bug 27661. Added comment about this bug there.
27661 already has at least 10 duplicates...should be tagged mostfreq.
Changing component.

Verified, this is a duplicate of bug 38488 "Can't use an HTTP/1.0 proxy like
Junkbuster without changing debug prefs."
