185216 - Dropdown List Vanishes on mouseup (WORKAROUND AVAILABLE)

Status: RESOLVED DUPLICATE of bug 154670

(Core :: Layout: Form Controls, defect)

Description

[Justin Bartee]

The dropdown listbox vanishes upon mouse up.  That is, single-clicking on the drop
down listbox causes it to "flash."  The particular listbox I referenced contains
a relatively large number of selections.  Other, shorter dropdowns don't have
this seem to have this bug.

NOTE: This bug has already been reported, but I could not find reference to the
workaround.

Reproducible: Always

Steps to Reproduce:
1. Single click the dropdown list as normal (click and release immediately)


Actual Results:  
The dropdown list flashed.

Expected Results:  
The dropdown list should have dropped down as usual and allowed scrolling/selection.

There is a workaround for this bug:  doubleclick the dropdown list.  DO NOT move
the mouse, or the list will disappear.  Use the arrow keys to scroll through the
choices and the return key to validate the selection.

Bug number?

dupe of "drop-down select menu closed by DOM/CSS events."

I think the workaround (at least the double-clicking part) has been mentioned in
one of the many dupes, but in the future, please just comment in the original bug
