    <thetext>I was able to reproduce these failures at Ventura Debug ToT on Apple Silicon running the tests as follows:

run-webkit-tests &lt;test_goes_here&gt;

I have marked the expectations for this test prior here:

    <thetext>(In reply to Robert Jenner from comment #3)
&gt; I had initially assumed that this was a macOS Ventura 13.3 regression. After
&gt; further investigation I found that wasn&apos;t the case, and that our range
&gt; appears to be 262625@main-262645@main.

Disregard this. It actually was a macOS 13.3 regression. It appears to be a commit regression. However, the last time it was passing it was running on macOS 13.3, but the WebKit built product was build with Xcode 14.2, which wouldn&apos;t have had the macOS 13.3 SDK yet. The next build was after we upgraded the bots to 13.3, and the builders to Xcode 14.3. That&apos;s when the constant failures started. 

Just to confirm I downloaded a build that was older than the last known passing point (262625@main) and it still failed.</thetext>
