[web] engine LUCI does not fail tests that should fail #78072
Description
This PR broke some framework tests: flutter/engine#24903. For example, running the following command with the PR will consistently fail, as expected:
flutter --local-engine=host_debug_unopt test --platform=chrome test/material/tabs_test.dart
However, that PR was green on LUCI both pre- and post-submit:
The tabs_test.dart did run as part of the LUCI build with the following command and it does attempt to use a local engine build, but it didn't fail (complete log):
../../bin/flutter test -v --platform=chrome --web-renderer=html --sound-null-safety \
