During selection we were checking if the clip belongs to a group or not and pass that single clip or all the clips belonging to its group to timeline.Selection.set_selection(). But while unselecting we creates a temporary GES.Group to hold them. So in the above mentioned 'if case', it got confused as a group created by user and passed all elements inside it to be unselected.
TODO:
- Fix test case (
test_timeline_timeline.TestGrouping.test_can_group_ungroup) - Write new unittests
Fixes #2433 (closed)
