Comment 1 for bug 1108064

Here's a similar buggy behavior, with a certain kind of dialog:

If you edit a Firefox bookmark from the address bar, a dialog comes up. I guess it's a particular style of window in X, 'cause most dialogs don't behave the same. The bookmark properties dialog includes a button for "Remove bookmark", and Alt+R is the keybinding. But as soon as you hit alt, that dialog goes away, and the HUD comes up.

You might or might not categorize this problem under this bug. Thanks.
