<!--
NOTE: This intentionally does not use description() and does not include js-test-post because
doing either of those things made the bug go away.
NOTE: This intentionally does not use the name `CSS.escape` because that function exists now but
did not when this test was added. The name was changed to `CSS.layoutTestEscape` for this test.
