Facebook comments, empty div underneath

occasionally several empty div tags ar开发者_开发技巧e created under the comments block. They all have an id like "bootloader_**" and takes up space.

Why is this happening? Thanks.

This is coming from the Facebook parser. Unfortunately, you won't have any control over that.

Actually, you could possibly (not sure as I've not tested it) use jQuery in order to remove any bootloader_ tags.
