Bug 1878207 [wpt PR 44370] - Always call superclass in HTMLLabelElement::DefaultEventHandler, a=testonly

Automatic update from web-platform-tests
Always call superclass in HTMLLabelElement::DefaultEventHandler

HTMLLabelElement::DefaultEventHandler does not currently call up to
HTMLElement::DefaultEventHandler in many cases. This patch makes sure
that HTMLLabelElement always calls up to HTMLElement, which makes
<label>s in <button>s work.

WebKit's HTMLLabelElement already does this in all branches of
HTMLLabelElement::defaultEventHandler since 2017:
WebKit/WebKit@fec9c1d
WebKit/WebKit@b9bad31
