Summary
This fixes an issue in the formatter where it reorder comments or, worse, moved trailing stub function comments into the next's function body.
The problem is that the formatter uses
line_suffixfor the trailing comments and the line suffixes are only flushed after the next newline. However, there's no such newline directly after the comment(s) because the formatter now allows newlines to be omitted between stub functions.The fix of this PR is to match Black's behavior to insert the empty lines if a collapsed stub has a trailing comment. I'm not very fond of the empty lines, because I think the comments should remain close to the stub body and not be separated by empty lines but it is consistent with how we format trailing function comments in other places and matches Black.
Closes #11569
