name: Blank lines inside a multi-line directive do not end the comment
why: CommonMark ends a comment block at its closing delimiter, not at a blank line, and prettier honors a marker written with blank lines around it. An implementation that closed the run on a blank line would read the content as empty and quietly stop exempting anything, which is the damaging direction: a break an author marked would be joined with nothing to show for it.
