REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura (13.5, 22G74/arm64) using the following command:

rwt --clobber-old-results --verbose inspector/sampling-profiler/many-call-frames.html

REGRESSION:

There seems to be a clear regression point at 267655@main, as the issue began constantly failing then (issue did not reproduce at 267654@main).
