Add necessary features to allow parallelism with Playwright

[MisinformedDNA]

I want to use xUnit with Playwright, but xUnit limitations make that an unappealing option due to non-parallelism. You said:

Our feature is explicitly designed... to maximally utilize the compute resources of the box. Limiting the number of tests to be started (whether executing or not) will dramatically reduce the performance of the framework.

But not being able to run any tests in parallel is a huge step back in performance and gives MSTest and NUnit a huge performance advantage.

You've obviously have been opposed to this in the past, but I'd ask you to reconsider to enable xUnit to work in more use cases. Because as it stands right now, sorry, but xUnit just doesn't cut it.

@MisinformedDNA I don't understand this feature request. What is missing in xUnit to allow parallelism with Playwright? I'm using xUnit with Playwright and the parallelism seems to work fine.
The linked "xUnit limitations" issue doesn't seem to point to any xUnit limitation with parallelism.

Can you clarify what the actual issue is?

Not trying to antagonize, but it appears as though there may be a bit of a smoking gun here
