[luatex] Bug: Wrong behaviour of \limits

Dear luatex devs,

if I place \limits after a math atom, i.e. {}, no error is thrown. 
luatex should throw "! Limit controls must follow a math operator." as 
the pdftex and xetex engines do.

Minimal example:


It will typeset using luatex but will throw an error when processed 
using pdftex or xetex.

Kind regards,
