Trevor can you look at this one?

Attachment: Failure log from layout/generic/test/test_selection_expanding.html

For what its worth, I am running into this as well in:

  layout/generic/test/test_selection_expanding.html

This is in a win8 vmware fusion instance.

Note, it does not trigger when running the test alone.  You have to run it
using the multi-test harness by specifying the layout/generic/test directory,
etc.  This log only shows the one test case because I hacked out the rest from
the makefile temporarily.

I can't reproduce anymore atleast with jesse's test case, and I don't have a win 8 machine to test on, so closing as wfm if someone can still reproduce please reopen.  If I had to guess I'd say this was fixed by bug 862863.

I'm not sure why accessibility is on here, maybe because windows 8 touch stuff?

I can't reproduce now with my testcase either.

Ben Kelly -- instead of reopening this bug, please file a new bug report if you can still reproduce on trunk.
