Commit 353ce5344fbde5a6cecbdd2c131e1cf0f4b7f383 made QMenu::exec()
return immediately (without showing the menu), which meant it never
emitted aboutToHide() and QToolButton didn't reset mouseButtonDown.
Therefore, on the next click on the toolbutton (maybe by then the
menu has actions), it won't even try to show it (because mouseButtonDown
is still true).
