This is probably what is causing the tests to fail. I haven't looked any more deeply.

Visited during wg-debugging triage. It looks like the //ignore macos annotation on this test has turned into a more generic // ignore lldb annotation. There is some work happening to re-evaluate these kinds of disabled tests in (#95696) so this might get changed there. If not, the first step here is to retest on a recent macOS & XCode release.

This seems to have been fixed in #129218, specifically e93e610.
