When you set the end of the narrowed region at the middle
of the sentence either in text-mode or in C-like languages,
then use forward-sentence to move the end of the narrowed region,
then widen with 'C-x n w', point will be not at the end
of the sentence.  This behavior makes no sense.

Regardless of the fact that treesit-forward-sentence works
differently from forward-sentence, their both results make no sense.

There is no meaningful difference whether to keep point at its old
position as treesit-forward-sentence does, or move point to the
middle of the sentence as forward-sentence does.

So I think there is no bug here.
