Action from a context menu on a popup dialog is not triggered

In our application we have a 'popup', which until now was actually a window, but which we wanted to turn into an actualy popup, by passing the `Qt::Popup` flag.

As it turns out, when changing the flag, suddenly the actions in the context menu we create from a QTextEdit instance inside the popup are not triggered anymore (including Qt-default constructed actions)

I tried to creating a minimal example that reproduces the problem. It seems I can't attach a file while creating this issue, but I'll attach it once the issue is created.
