Menu associated with launcher tile right click does not disappear when it should.

[Springnuts]

In order to close Thunderbird I right clicked on the Thunderbird icon/launcher tile in the side bar.

As expected a white text on black menu appeared. I closed Thunderbird (can't remember how) but the menu remained on the screen. It was not 'active' (ie clicking on the options did not produce any effect).

Ex0ected behaviour was for the menu to close as soon as the program closed, or if, eg, another menu was opened.

It eventually closed by itself (as I started to report the bug)

See screenshot of the unresponsive 'zombie' menu.

I should add, the menu remained at the front of the screen - ie it hid that area of any other program opened on that screen.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

I suspect this is caused by bug 1932328 so we should at least wait for the fix for that.
