A good point.

Closing as there may not even be a bug here. Even if there is, it is upstream.

As you have identified, this is an upstream issue.

You would be best reporting it using bashbug(1). Bash appears not to have a
public bug tracker, so I cannot see if it has already been reported.

Thanks

Dear Maintainer,
When executing:

$ echo "${Var#*'$('}"

I see an error:
bash: command substitution: line 6: unexpected EOF while looking for 
matching `''

instend of the expected result of cutting off part of the text.
dash and busybox ash work as excepted:
$ echo "${Var#*'$('}"
Example2)
