XPath evaluates to current node for expression .. #38553
Description
Describe the bug:
We should retrieve the parent node with .. as xpath. Instead, we still retrieve current node.
To Reproduce:
./mach run -r <following-file> --pref=dom_xpath_enabled
<button id="check">evaluate xpath for parent </button>
<script>
document.getElementById('check').addEventListener('click', () => {
const result2 = document.evaluate("..", document.getElementById("check"), null, null, null).iterateNext();
console.log(result2);
});
</script>
