Thank you for bringing this up! 🙏
I've updated the PR title to be more precise.
We meant to say theme.direction.rtl instead of theme.rtl. 😉

@LukasTy Do we have a docs section about RTL?

I found this about extra unicode characters, but no section about how to setup RTL like for the data grid https://mui.com/x/react-data-grid/localization/#rtl-support

Do we have a docs section about RTL?

No, we don't. 🙈
That's a great idea! 💯
Created an issue: #11523. 😉
