@a-siva - it looks like @leafpetersen 's fix landed:

https://dart-review.googlesource.com/c/sdk/+/144220

Can you roll this forward and re-run?

Tests are passing for me on chrome, but i seem to able to repro the firefox breakage. Just sanity checking that they run on a clean branch.

@yjbanov @sigmundch - fyi, other issues appear to be fixed, but we're now seeing a new felt error here:

00:36 �[32m+336�[0m�[33m ~24�[0m�[31m -1�[0m: test/text/font_loading_test.dart: loadFontFromList loading font should send font change message �[1m�[31m[E]�[0m�[0m                                                                                 
  TimeoutException after 0:00:30.000000: Test timed out after 30 seconds.

Is this possibly a flake?

It appears to be a flake, the same issue is also seen in the engine buildbot from time to time

I take that back, the time out we are seeing here is different from the one the engine buildbot is flaking on (scenario_app unit test). This PR appears to be timing out loading some fonts.

@yjbanov @ferhatb - have you seen this error before (Mac Web Engine)? (test/text/font_loading_test.dart: loadFontFromList loading font should send font change message)

The same test appears to pass on Linux. Is there a way to rerun the Mac one?

It has been re-run once already

THe re-run is happening at https://ci.chromium.org/p/flutter/builders/try/Mac%20Web%20Engine/2632

Looks like your new run is green?

Is it possible to kick off a framework test run with this version of the engine?

Submitting the PR to do a trial PR of the framework.
