Test various cases when we constrain a selector matching to a subtree selected by #ID

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


Missing id.
PASS document.body.querySelectorAll("#notThere *").length is 0

ID is adjacent of target.
PASS document.body.querySelectorAll("#directAdjacentRoot+div li").length is 1
PASS document.body.querySelectorAll("#directAdjacentRoot+div li")[0].id is "directAdjacentTarget"
PASS document.body.querySelectorAll("#indirectAdjacentRoot~div li").length is 1
