The Transition middle pane tab remains connected to transition clip removed as part of an undo/redo operation
Steps to reproduce:
- Create a new project
- Add two color clips
- Overlap the clips to create a transition
- Click the transition clip to select it
- Undo, notice the Transition tab in the middle pane still appears connected to the clip.
- Alternatively, move clip2 such that they do not overlap anymore, notice the same.
First we should have two unit tests which create a
TransitionsListWidget object, one which performs and undo and one which moves clip2 as described above. The tests can check that the object is updated and properly fail. Then, the issue shall be fixed and the tests shall succeed.
