They were previously overwriting the root element, which is probably
the kosher way of handling it, but was making it impossible to call
.remove() on a view without making the DOM unusable for every other
view.

Will need to investigate if there's a "proper" way of doing this, or
if perhaps this is exactly what you're supposed to do.
