Comment (by noisysocks):

 Replying to [comment:157 jrf]:
 > @isabel_brison Where are the tests to accompany [52380] ? There is no
 safeguard in place now to ensure that this patch does not break something
 else.

 It's a new function added in WP 5.9. Unfortunately there aren't unit tests
 for the function though there may be some E2E tests in Gutenberg that
 cover the behaviour. @youknowriad would know for sure. I wanted to fix
 this as it's a very prominent warning when visiting any page on a WP 5.9
 site running PHP 8.1 🙂
