Like the rest of the profile, it duplicates the allow rule and wraps one side in the check for ENABLE_SANDBOX_MESSAGE_FILTER. I was hoping this would do for now, as it matches what the other code looks like, but I'd be interested to see if there was interest for cleaning this up a bit in across all the message filters in a future patch. 1779446 4 434204 pvollan 2021-07-26 08:01:00 -0700 Comment on attachment 434204 Patch R=me. 1779447 5 webkit-bug-importer 2021-07-26 08:01:36 -0700 <rdar://problem/81108098> 1779795 6 ews-feeder 2021-07-27 11:14:29 -0700 Committed r280345 (239992@main): <https://commits.webkit.org/239992@main> All reviewed patches have been landed.
