I've seen this fail in a few builds so filing a known issue for it. From history, it's failed 10 times in the two weeks:

@tmat this test has been timing out sometimes. Can you take a look? Is the set of tests just slow or is there something else going on? Note that we break the tests up into separate work items based on the test class so one option is to split slow tests in to separate classes.

#40006 Looks like Daniel filed a ticket that better detected these failures so there's a bunch listed over there.

closing in favor of daniel's issue. @tmat, look at #40006 for all the timeouts being seen in builds from this test.

@marcpopMSFT Unfortunately, there is no memory dump or test output log, so hard to find out what's wrong. I'll try to run the test in a loop locally.
