In Shell-script mode, the second opening parenthesis in $((var+1)) has
a different color than the first one (i.e. it is colored as the
expression within).

Not a big deal, if the expression is as simple as above, but if the
expression itself contains parentheses, then the bad coloring gets
distracting, because the color of the expression may switch off in its
middle due to a closing paranthesis within the expression.

It is clear that the coloring in emacs 28 is intended for the command
string in command substitution, but unfortunately it is triggered by
$(( as well.

Yup.  This was also noted in bug#13241 from a different point of view,
so I'm merging the two bug reports.
