 An own-line comment before a member's `.` stays before it, for `.b` and `.#b` alike.
 Prettier moves it before the object for `.b`, and after the `.` for `.#b`; both cross a token.

+A binary-like or conditional object of a member breaks its parens the same way for `.c`, `[c]` and `?.[c]`.
+Prettier does so for `.c` only, while an `await` / `as` object breaks them for `[c]` too.
+The computed property (`a[b + c]`) keeps its own layout.
