r17094 seems to have broken fast/repaint/4774354
r17094 was for <rdar://problem/4776665> REGRESSION: In Mail, caret is visible when the message body isn't focused
The broken test is for <rdar://problem/4774354> REGRESSION: In Gmail, caret reappears when dragging a selection over some text in the message body

The test was working here:
and broken here:
Build details for those builds are here:
As you can see, the only revisions added between those two runs were r17093 and r17094. Perhaps it was r17093 that did it?
Wow, I was too tired when triaging these failures last night. This test has been failing since its introduction. Seems like it was checked in with wrong results. This can't even really be called a regression.
