## Summary

Fixes https://github.com/astral-sh/ruff/issues/7448
Fixes https://github.com/astral-sh/ruff/issues/7892

I've removed automatic dangling comment formatting, we're doing manual
dangling comment formatting everywhere anyway (the
assert-all-comments-formatted ensures this) and dangling comments would
break the formatting there.

## Test Plan

New test file.
