We have some false positives. It is no longer necessary to add parentheses around the
inexpression that is already in parentheses.We need to check the

Can we proceed with some false positives for now and refactor them outside? If you prefer, rewriting the fixer to work outside in is also fine.

I plan to leave a TODO for now, as this is a very rare edge case and has no negative impact.
