Code Review
This pull request adds a regression test to ensure that TabBar does not crash when it is in a 0x0 environment and an animation is triggered. The test correctly sets up the scenario by resizing the view to Size.zero and then animating the TabController. The test is well-written and follows good practices, including proper resource disposal using addTearDown. The change is approved.
