where how should we fix it? If unrelated to updated Xharness, I can merge this PR, right?

[pavelsavara]

It is coming from xharness
https://github.com/dotnet/xharness/blob/e5857fbbc3f1d39d2776af5a5e3235c9ff485afa/src/Microsoft.DotNet.XHarness.CLI/Commands/WASM/Browser/WasmBrowserTestRunner.cs#L255

Easiets fix is to add the option processing into WasmTestRunner.cs on this branch.

You can't merge this as is, it breaks all WASM tests

[kotlarmilos]

Xharness now installs correctly

Easiets fix is to add the option processing into WasmTestRunner.cs on this branch.

Added

Should be ready for merge
