I've sent a PR to disable this test for Mono to unblock the CI #40837 and moving this to 6.0

@jeffhandley @marek-safar how area owners should handle Mono-specific issues?

Thanks, Adam! We'll want to put a little more time into this later to try to narrow it down to see if we can find the appropriate mono area that we would move it into. But since we've already punted this out to 6.0.0 and disabled the test for now, there's no urgency on it as far as I'm concerned.
