Description Jessie Berlin 2012-05-22 14:26:36 PDT 
This test was Skipped on WK2 due to WTR not having an eventSender.keyDown implementation. Unfortunately, the fix for https://bugs.webkit.org/show_bug.cgi?id=57515 missed an block in the Skipped list that should have been removed, so it has not been running.

When cleaning up the WK2 Skipped list, I noticed that this test crashes when run under WK2:

Note: I first noticed this on Lion with r118050
Comment 3 Alexey Proskuryakov 2015-04-28 15:37:59 PDT 
This doesn’t crash for me now, I made many fixes to this code a year ago.

Will unskip.
