[Vangelis Evangelou]

Hi Arash.

Thanks for your comment. I submitted it as an emacs bug, with bug id #70816, in case you want to comment there.

Best,

Vangelis

This is what I see with "emacs -Q":

Since it happens with vanilla Emacs & tex-mode.el as well: Can you
please submit a bug report to Emacs with a recipe starting with "emacs
-Q", so the developers there can reproduce it?  I could re-assign this
report, but I think it makes sense to start a new one with a clear
reproducer.

TIA.  Best, Arash
