w3c bug over here: https://www.w3.org/Bugs/Public/show_bug.cgi?id=16816
The basic gist is that I'm trying to use a menu on several elements to trigger further actions on the site (search a different section, add user to friends list, go to a different section for the same result rather than the section the result link takes you to when clicked) based upon the textContent of the search result element.
The click event for a menuitem doesn't seem to indicate which page element a context menu was triggered on, meaning you have to add an event listener to the contextmenu event then set a variable accessible from the menuitem click event handler's scope (see http://pastebin.com/7kS8tu2W
for example of this workaround).
Similarly, the show event for menu elements don't indicate the element that triggered the context menu.
