This reverts commit 8a8d599 and includes a regression test, as well as a tweak to a log message. Essentially, the broadening was improper. We have to be careful when dealing with suffixes as opposed to prefixes. Namely, my logic previously was that the broadening was okay because we were already doing it for the reverse inner optimization. But the reverse inner optimization works with prefixes, not suffixes. So the comparison wasn't quite correct. This goes back to only applying the reverse suffix optimization when there is a non-empty single common suffix. Fixes #1110 Ref astral-sh/ruff#7980
