MenuItem at times do not trigger activate signal

[godiard]

This was reported in AU, but I could reproduce it:

Once in a while (~1 in 10) when the user try to copy a item in the Journal, to Documents or to a external device, nothing is copied.

After add log, I found the code connected to "activate" signal is not called [1].

I added a call back to "button-press-event" and that is always called.

There are other bugs reported similar to this, but not exactly equal [2] and a complex proposed workaround [3].

I couldn't find a solution to this issue. Attached is a minimal testcase, to show MenuItem is not sending the 'activate' signal every time than is clicked.

In the attached example, the 'activate' signal is emitted one in two clicks, or when the mouse is pressed for a long time.

GtkMenuShell button_release complicated logic can be involved in this issue:
