Thanks, do you have any examples of how e.g. the logic in
selectionHasStyle could be tripped up by (or be insufficient for)
block styles like this? Is it a matter of having it not query the
alignment for non-block elements when traversing nodes (because it
might return an invalid value?), or something else?
