<!--
  We test this separate from click because the spec as of
  https://html.spec.whatwg.org/commit-snapshots/4ba46b025ec806ded7b4911bf8f9dd7bf9ff365e/#location-object-setter-navigate
  referenced click handlers specifically, instead of using the general user activation concept which
  includes other events like mouseup.
