Also worth noting that this bug was initially found as a result of upgrading from 2020.3 to 2021.2 and so I'm seeing it as a performance regression between versions.
It's interesting that the QA team found it started to reproduce between 2021.2.0a21 and 2021.2.0b1 which implies that the change is contained between those versions
