Seems like this test randomly crashes (not always) any other test from `TabPaneTest`. It might be crashing the test
executed just after this one OR the next test which does `tk.firePulse()`. Also not including `tk.firePulse()` would
make the test incomplete/ unreliable.

That is better to include the test now, else very doubtful of adding it in future. Including the test in next commit
with @Ignore("JDK-8242621").
