Summary [WK2] fast/forms/input-search-press-escape-key.html crashes

Reported 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: Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception
