I don't think we should do this. This would result in another round of Apple-style-span nightmare.

This is actually broken because convertFixedAndStickyPosition doesn't adjust coordinates with respect to the wrapping div's. r-.

Oh oops, I completely misunderstood this patch :(

I think we should check settings in createMarkupInternal though.

We don't need this separate boolean because fullySelectedRoot can only ever set to body.

I'm going to keep the separate boolean because it gets read twice, and it is conceptually different than the comparison that it gets set to
