 Hi @ecparkin, welcome to Trac!

 This appears to have been introduced in WordPress 5.9 when changes
 included in Gutenberg 11.4.0 were added to WordPress.

 On WordPress 5.9, the error is shown.
 On WordPress 5.8, the error is not shown.
 On WordPress 5.8 with Gutenberg 11.3.0, the error is not shown.
 On WordPress 5.8 with Gutenberg 11.4.0, the error is shown.

 I have opened [https://github.com/WordPress/gutenberg/issues/39395 an
 issue on the Gutenberg repository] so that the folks over there can
 investigate this further.

 I'll close this ticket so that discussion can be focused over there.
