Particularly sorting. Reproduction shown by ESA. Sorting on any column, and then trying to close the ED browser makes it hang. Reproduced by @lxatrhea on local machine.

Update: seems that the problem is persistent to other browsers as well.

This happens when RevisionNumber is reset to 0 for all ViewModels in the IME. This typically happens on Dispose of the Browser. Somehow, the NotifyChanged event is handled by DevExpress and some code is executed when a filter or sort is active on a TreeListControl, which leads into a repaint/refresh of the UI.

verified with 9.6.0.0

various tests performed which would lead to crash, now not happening anymore, ED browser correctly disposed

this fix is for all views that provide the mentioned filtering and sorting capability and is not limited to the ED only
