SUMMARY

Before, the "Show textual list" popup when clicking a grouped task would disappear if you click elsewhere, or one of the entries in the list. Since this was switched to use PlasmaPopupWindow instead of PlasmaCore.Dialog, it no longer does - the popup sticks around (possibly hidden by other windows, as it can go below them). 

This blocks the next click on a grouped task (which now closes the existing popup, rather than opening the one for the clicked task), blocks Task manager tooltips while open, and may inappropriately cover open windows after it's served its purpose.

STEPS TO REPRODUCE
1. Set task manager to group tasks and set it to "Show testual list". Go to a clean workspace. Open two Konsole windows.
2. Click Konsole to open the popup, select one of the windows. (Or click elsewhere)

OBSERVED RESULT

Popup is still open.

EXPECTED RESULT

Popup is closed.
