Comment:

 Flagging that this bug fix caused a major performance regression and
 effectively reverted most of the benefit that [56805] introduced. See
 [https://wordpress.slack.com/archives/C02RQBWTW/p1696950609355169?thread_ts=1696880738.627909&cid=C02RQBWTW
 Slack thread].

 While a functional bug fix is more important than a performance
 improvement, I am reopening this so we can further explore alternative
 ways that get us closer to good performance while maintaining
 functionality as needed. The performance impact of the change is
 significant enough to warrant that IMO.
