Tweaks to get functional with injected HTML

* content must be run through `$compile` in order for directives to
  be picked up. When when it is compiled, the content has not been
  put into the DOM yet, so we can't calculate the appropriate
  coordinates. This change delays that until the user scrolls. This is
  not ideal, but provides the correct behavior for the time being.
