357475 - Selection / highlight in context menus doesn't work when holding down mouse button

Status: RESOLVED FIXED

(Core :: Widget: Cocoa, defect)

Description

[Bryan Blackburn]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20061019 Minefield/3.0a1
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20061019 Minefield/3.0a1

When opening a contextual menu (on a page, the tab bar, and bookmark bar at least) with a right- or ctrl-click and hold, the menu is not yet selectable.  The menu is "frozen" (for lack of a better description) until the mouse button is released, then items can be highlighted and selected by another click.  This is not Mac-like and not how such menus have worked previously (20060925 was my last nightly, which worked properly).

Reproducible: Always

Steps to Reproduce:
1. Open Minefield
2. Right- or ctrl-click on the page itself, holding the mouse button down
3. Try to move around the menu, noting no highlighting occurs yet
4. Release the mouse, now you can highlight to select an item

Actual Results:  
Items cannot be selected while holding the button, it must be released, then another click to select the item.

Expected Results:  
Items should be selectable simply by moving to the given item and releasing the button (like all other menus on the Mac).

Regression from the switch to Cocoa widgets?

Changing summary and confirming...

I've just discovered the proximate cause of this bug:  As long as you
keep the mouse button down (the left one when you've ctrl-clicked or
the right one when you've right-clicked), the OS sends mouse-dragged
events to the window (the NSWindow) from which the context menu was
popped up -- not to the context menu's window.

Now I need to figure out how to change this :-)

Fixed by patch for bug 387164, which just landed on trunk.
