[issue42893] Strange XPath search behavior of xml.etree.ElementTree.Element.find

Thanks for the pointer. I didn't notice this paragraph.
xml.etree.ElementTree.Element.find currently returns None if XPath expression is invalid or unsupported. I think it should also return None if position predicates are not preceded by a tag name. It would be even better to emit warnings or raise exceptions to indicate any errors.
