This isn't a bug, but the expected result.

Your comment (because it's a comment, even though it is a fancy one) is technically attached to the import statement right after, because there aren't any newlines.

If want to have your comments to be "sticky", you have to add a newline after the comment.

This is called "group" and it's explained in the relative chapter of our docs: https://biomejs.dev/analyzer/import-sorting/#grouped-imports

If you feel strongly about this kind of comments, feel free to open a discussion with concrete ideas on how support these cases
