Steps to reproduce:

1. Set small (10 sec) refresh interval by clicking the upper right corner of Problem by severity widget.
2. Click on any problem counter from any group to open a events popup.
3. Mouse over the icon with number of actions in the Action column to open actions popup.
4. Wait for the automatic refresh of the widget.

Result:
The event popup automatically closed, but the action popup remains on screen in the unclosable state.
Expected:
All popups should close after widget refresh.
