It's a bit bugged with iframes, I'm sure you've noticed.
Probably hard to fix though

@allmeta, yeah, I'm aware; however, I can't fix it at the style-level. You should consider reporting it to Vimium maintainers instead. (Just search through the known issues beforehand to make sure it's not already reported so you don't create a duplicate.)
