> This PR adds a regression test for the "retroactive" behavior of `@SuppressWarnings("dangling-doc-comments")`, that is,  the warning suppression applies to comments preceding the declaration that the annotation annotates, even though those comments are not within the lexical scope of that declaration. Previously there was no test for this behavior.
