38459 - Selecting a popup menu item fire an onclick event on the element under the menu

Status: VERIFIED WORKSFORME

(Core :: XUL, defect, P3)

Description

[Jean-Francois Ducarroz]

This problem occurs with the autocomplete XBL widget. When the user select a item with the mouse in the popup 
menu, the element right under the popup menu will receive the mouse click event. I am expecting that the popup 
menu will fully consume the event.

This problem is kind of blocking for the message compose window has a mouse click in the addressing widget will 
force the creation of a new row and move the focus in it. Sometime the subject line receive the event and therefore 
the focus is switched to the subject line.

Same seems to be reported in bug 38442.
Is this new at all? Been seeing it now and then for "ages"..

hmmm, i haven't seen that behavior. xpmenus seem to be alright, as do context 
menus (in that they don't pass the click through to the content area below the 
popup). I'll take a look.

I will try to write a small test case. Until then, you can see the problem with the msg compose window if you turn 
on the autocomplete menu, for that you need to modify mozilla/mailnews/compose/resources/content/
addressingWidgetOverlay.xul:

change line 79 to be: displayMenu="true"
