fast/attachment/attachment-disabled-rendering.html
Is a 'Missing text' failure on iOS EWS.

The issue does not appear in the results database and is interesting because it has an "Image", DIFF, and STDERR.

HISTORY:
https://results.webkit.org/?suite=layout-tests&test=fast%2Fattachment%2Fattachment-disabled-rendering.html

The first build I've seen this on EWS is:

Marking expectations to help EWS r292568

It looks like Tim adjusted the test here: r292306 which is also the first time it started failing. Suspected regression point.

Failure is not visible not only on iOS but also in history.

Rebaselining the iOS result should be fine in this case.
