bug#55796: Command highlighting deactivated on spaces

I am using sh-mode and have noticed that using

delim=$(numseq-delim "$2")

highlights the command numseq-delim

But when there are any spaces between $( and the command name
numseq-delim, the highlighting gets deactivated.

You don't say which Emacs version this is for, or what mode you're using
or what language this is.

In Emacs 29, in shell-script-mode, numseq-delim receives no highlights
with or without a space after the $(.

I am using GNU Emacs 27.2 with sh-script.  I am using $() to run commands from a bash script.  The command name gets highlighted if there are no spaces, but no highlighting is done if there is a preceeding space.

Actually, it was good to have highlighting of the command, even when there is a space between $( and the command name.

Thanks; with the following I'm able to reproduce the problem in Emacs
27.2:

#!/bin/bash

delim=$(numseq-delim "$2")

delim=$( numseq-delim "$2")

But not in Emacs 29, so it has been fixed now, and I'm therefore closing
this bug report.
