@radekdoulik, are we able to fix it in 7.0?

[radical]

@ilonatommy do these tests still fail? Has the failure changed?

[ilonatommy]

You're right, running dotnet build /t:Test src/libraries/System.IO.FileSystem/tests /p:TargetOS=Browser /p:Configuration=Release /p:RunAOTCompilation=true results in [PASS] for all 48 kinds of CopyFileWithData.
