LayoutTests/StaleTestExpectations

 # This file is for TestExpectations entries whose bugs haven't had any activity in 3 months.
 # Only imported test suites, virtual tests or platform/configuration-specific lines should
 # be moved here. The tests for stale cross-platform lines should just be deleted.
 #
 # Feel free to take ownership of any of these lines and get the test passing.
