Likely caused by: #106014, potentially due to unintended side effects. Compare range: 105bf4d...48aa315

This is a mix of regressions that appear to potentially just be noise and ones that are clearly not just noise, so keeping them all.

Closing this out as many of the results show a bi-modal or multi-modal history, and the results are otherwise acceptable.
