Blocking an anchor doesn't stop the user from clicking on that anchor

[rwencel]

Block an anchor on the page, then click on it. It will trigger the anchor instead of being blocked.

I tried adding "click" to the bind function, but the handler function is still never called.

I updated blockOverlay with an onclick event handler that returns false and stopPropagation/preventDefaults to prevent the anchor from seeing the click, but that doesn't seem right.
