212658 - context menus open on mouse-up instead of mouse-down (like regular menus)

Status: VERIFIED DUPLICATE of bug 89308

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

Description

[Daniel B.]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030612
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030612

Context menus context menus open on the mouse-up event.  

Not opening on mouse-down is inconsistent with many other Mozilla and non-
Mozilla menus and similar GUI elements:

- Mozilla menu-bar menus
- Mozilla pull-down boxes (e.g., the location box)
- MS Windows context and menu-bar menus
- Netscape 4.x on Windows and X11 (I think; I can't confirm that right now)

Also note that requiring a mouse-up event makes using menus slows and
less efficient for users.

Reproducible: Always

Steps to Reproduce:
1. Point to something that has a context menu, for example non-active part
   of a web page.
2. Press and hold the right mouse button
3. Release the right mouse button

Actual Results:  
Context menu appeared after releasing button.

Expected Results:  
Displayed context menu on button-down event.

Verified dupe.  Note that saying that "MS Windows context... menus" open on
mouse-down is incorrect.

Ack!  Why does the search on the bug-report report page never find
the bug report I'm about to duplicate?
