[Dev-luatex] Using \global with \toksapp

Dear list,

Trying to use \global with \toksapp, e.g. when saying 
»\global\toksapp0{}«, luatex throws a fatal error:

This is LuaTeX, Version 1.13.0 (TeX Live 2021/dev)
  restricted system commands enabled.
**! This can't happen (prefix).
<*> \global\toksapp
!  ==> Fatal error occurred, no output PDF file produced!
Transcript written on texput.log.

While I know \gtoksapp exists, this seems surprising nevertheless; the 
error message seems to agree. Is this indeed unintended?

Best wishes, Esger Renkema
