Loading more history, I see a failure with r251038, so it's more of "as long as we have history" case.

macOS wk2 Release, this test was consistently passing until approximately at 251105@main, the test began to flaky timeout.  

macOS wk1 Release x86_64 on one bot at approximately 252062@main, the test began to flaky fail when brought online and has continued since that time.  There is no other bot for this configuration, so no one-to-one comparison cannot be made, but comparing against similar bots did not reveal any obvious differences.

Updating test expectations to reflect the current test status.
