/**
 * Our queries interact differently with composite and host elements, and some specific cases require us
 * to crawl up the tree to a Text composite element to be able to traverse it down again. Going up the tree
 * is a dangerous behaviour because we could take the risk of then traversing a sibling node to the original one.
 * This test suite is designed to be able to test as many different combinations, as a safety net.
 * Specific cases should still be tested within the relevant file (for instance an edge case with `within` should have
 * an explicit test in the within test suite)
