The assertion is here, and the child
node is the body element, but at the moment it looks like the body element has already detached from the document due to document.documentElement.innerText = String.fromCodePoint()
line in the test case (presumably, I don't know exactly what String.fromCodePOint() returns).
What I don't quite understand is why PresShell::GetCurrentSelection includes detached nodes?
Maybe I am totally misundestanding these stuff since I am not familiar with them.

Looks like this assertion is harmless in this particular case since even if the child
is not a document node, we will end up not finding the corresponding node in the cloned document, thus we will ignore the node.
