Comment:

 I'm going to make an executive decision and close this for the same reason
 as #51894. An invalid callback is a clear developer error and should not
 be ignored. The fact that what used to be a PHP warning is now a fatal
 error is unfortunate but valid, and it does make it much more visible that
 a problem has occurred.
