HISTORY: https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.WebKitLegacy.RenderInContextSnapshot The history indicates that this is constantly passing, and that's true. However, we are currently set to use an iPhone SE (3rd gen) as the set simulator for API-test. This test passes there, but it fails on iPhone XS and higher. The test will need to be updated so that it doesn't become a constant failure, because we would like to move our simulator to iPhone 12 from iPhone SE.

After you have chosen your booted simulator it will choose to run on that simulated device, and not the one that we have set for our testing. 1957760 3 jenner 2023-05-24 17:10:28 -0700 *** This bug has been marked as a duplicate of bug 257235 ***
