Comment:

 Thanks for the ticket!

 As noted above, the steps to reproduce the issue on a clean install would
 be helpful here.

 As far as I can tell, core by itself should no longer throw this notice as
 of [54349] / #55967, though it's still possible that a plugin or theme
 passes `null` instead of a string to this function.
