### Fixed

- Second block comment on a line is lost and the next expression moves onto the comment line. A line that holds several comments and no code, such as `(* b *) (* c *)`, was read as one block comment next to code per comment, and there was no code on that line to attach them to. The first one ended up in front of the next expression, pulling it onto the comment line, and the others were dropped. Such a line is now one comment on a line of its own, printed as it was written. [#3487](https://github.com/fsprojects/fantomas/issues/3487)
- Idempotency problem when a comment follows a multiline infix expression in a let binding. A comment on its own line after `c +` and `d`, at the column of both, was attached to `d` rather than to `c + d`. That made the expression multiline, so the operator moved to the start of the next line, and on the next format the comment went to the whole expression and it was joined onto one line again. An indented comment now goes after the outermost preceding node that starts a line at its column, and only falls back to a node further along a line when there is none.
