Comment (by mikachan):

 Hi @isabel_brison, @bernhard-reiter. Pinging you both as I've noticed you
 as owners of similar tickets 🙏

 This ticket and patch is a backport of the PHP files from
 [https://github.com/WordPress/gutenberg/pull/53602 this Gutenberg PR],
 mentioned above. It's a bug fix that I believe should be included in
 either 6.4 Beta 3 or at the latest RC1. I'm unsure of the process from
 here around testing and considering it for commit. Hoping you can help,
 thank you!

 Also tentatively cc. @karmatosed for when you're back.
