+ * This test checks that the popupshowing event for input fields, which do not
+ * have a dedicated contextmenu event, but use the global one (added by
+ * editMenuOverlay.js, see bug 1693577) include a triggerNode.
+ *
+ * The search-input field of the browser-sidebar is one of the rare cases in
+ * mozilla-central, which can be used to test this. There are a few more in
+ * comm-central, which need the triggerNode information.
