Reverts #14061

Failure of CI test https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket.appspot.com/8895404291158004192/+/steps/run_test.dart_for_framework_tests_shard/0/stdout?format=raw

LGTM

[harryterkelsen]

That test should not be hitting the Roboto fallback code. That code should only be live if the FLUTTER_WEB_USE_SKIA environment variable is set to true

Then maybe something in our test infra is going wrong? @zanderso : maybe let's revert the engine roll first (flutter/flutter#45916) to see if the failure goes away. If not, then it's definitely an infra issue. CC @digiter @godofredoc .

[zanderso]

kk landed the engine roll revert.

[zanderso]

@liyuqian will you pause the roller?

[liyuqian]

@zanderso : paused now. Please feel free to resume it on https://autoroll.skia.org/r/flutter-engine-flutter-autoroll?tab=status once the root cause (either the infra issue or the engine commit) is fixed.

@hterkelsen @liyuqian the bot turned green after the engine revert. Other failures on the engine roll appear to be infra related, but I'm not sure about this one. @hterkelsen can you run the test locally with your change.

[harryterkelsen]

I just ran flutter test --local-engine=host_debug_unopt test/material with a tip-of-tree engine build and the tests are all passing

[harryterkelsen]

It looks like the failing test isn't even running on web.

[zanderso]

Okay. When the dashboard recovers from some other issues and turns green, I will re-enable the engine roller.
