https://results.webkit.org/?suite=layout-tests&test=fast%2Fediting%2Fdocument-leak-altered-text-field.html

This is the first test failure.

Looks like this fully resolved the issue, but TestExpectation hasn't been removed:

LayoutTests/platform/mac/TestExpectations:2732:[ Debug ] fast/editing/document-leak-altered-text-field.html [ Pass Crash ]

Chris, would you be willing to take care of this?
