I was able to reproduce locally, but I had to get creative since this was a newly introduced test, and since it was recently reverted there is of course no reproduction at ToT because the test was removed. Here are my steps: 

1. I downloaded Monterey Debug Build r292161 to test with. I chose that specific build because it was closer to the end in the range of revisions that this test failed on in the history. 

2. I was checked out to ToT, but just in the event that the test would not run, I reverted my checkout locally to r292161. I got the hashcode for that revision and did git checkout 6ddf72853c64be73426bce0a14fafa00690b3499

3. I ran the test as follows and was able to reproduce the failure: 

run-api-tests --debug TestWebKitAPI.WKWebsiteDataStore.DoNotCreateDefaultDataStore

ah! I didn't remove this line when landing the patch... that's why it constantly failed on bots and constantly passes on my local build (my local build is correct)
The fact that Truitt can reproduce it so easily makes me realize that; thanks!

... I will just re-land the patch as it should be
