Bug 487240

Depiction of the problem.

SUMMARY
When the menu depicted in the attached PNG file is visible, Plasma Shell becomes unresponsive until it is closed.

STEPS TO REPRODUCE
1.  Activate the Application Launcher plasmoid.
2.  Hover over an entry in the application list.
3.  Invoke its context menu.
4.  Select "Edit Application..."
5.  Switch to the "Application" tab.
6.  Interact with PlasmaShell to verify that it works at this point. It should.
7.  Select "Advanced Options".
8.  Attempt to interact with PlasmaShell.

OBSERVED RESULT
The sole thing I can get PlasmaShell to respond to is a (taskbar) panel unhide action, *if it's hidden*. Otherwise, nothing. Additionally, if it's unhidden when the window is invoked, after the window is closed, the panel shall not hide itself automatically until interacted with. It also appears to have a lagging effect upon screen recordings, as the attached recording demonstrates.

EXPECTED RESULT
The presence of the window shouldn't affect any of this.
