[Marta Darbinyan]

The following test became flaky after 300617@main both in Release and Debug.

imported/w3c/web-platform-tests/html/semantics/scripting-1/the-script-element/json-module/repeated-imports.any.sharedworker.html
Diff:
 PASS Importing a specifier that previously failed due to an incorrect type attribute can succeed if the correct attribute is later given
 PASS Importing a specifier that previously succeeded with the correct type attribute should fail if the incorrect attribute is later given
-PASS Two modules of different type with the same specifier can load if the server changes its responses
+FAIL Two modules of different type with the same specifier can load if the server changes its responses promise_test: Unhandled rejection with value: object "TypeError: 'text/json' is not a valid JavaScript MIME type."
 PASS An import should always fail if the same specifier/type attribute pair failed previously
 PASS If an import previously succeeded for a given specifier/type attribute pair, future uses of that pair should yield the same result

Marta: what makes this a regression from this? Looking at the history on the results database, it was flaky before that commit?

[Alexey Proskuryakov]

I don't see the flakiness. It's 100% passing between 300616@main and 298595@main. It was failing and flaky before that, but seems almost certain that it was for different reasons.
