Nothing in the spec says that this part should unconditionally run for the viewport and this is breaking on https://battle.crossuniverse.net/intro, making the page scrollable when it shouldn't be.
I wasn't sure what to call the test for this, so if anyone has better ideas, I'd love to rename it.
Also, yes, it needs to append the child with javascript, if the child is in the page initially, the bug does not occur.
