[radekdoulik]

@kotlarmilos looks like dotnet/runtime#84304 which should be fixed already

[kotlarmilos]

Correct, it has been fixed by dotnet/runtime#85048.

There may have been some other changes that caused the regressions.

[DrewScoggins]

Some tests are still regressed.

• Utf8Formatter.*
• Dictionary operations

[kotlarmilos]

Thanks for the heads up. I will go through your comparison and compare it against dotnet/runtime#77490.
