(un-cq'ing temporarily)

I didn't mean you could revert this change without at least discussing it with
me :).

How exactly did this change break you, and are you aware of the consequences of
using a directory that doesn't work correctly w/ TestExpectations?

Also, Douglas: are you using GN? I strongly think we should just make
run-webkit-tests work correctly with non-canonical output directories in the GN
build. I will implement this tomorrow if this will solve your problem.

re-CQ'ing. We will revert the error check for now and try to get a real fix
implemented tomorrow.

thx.
