Bug 1657152 [wpt PR 24873] - stopImmediatePropagation() should not un…

…register uninvoked 'once' listeners, a=testonly

Automatic update from web-platform-tests
stopImmediatePropagation() should not unregister uninvoked 'once' listeners

A 'once' listener should be unregistered when it is invoked, and
stopImmediatePropagation() should not invoke other event listeners.
We had a bug that stopImmediatePropagation() unregistered uninvoked
'once' listeners.
