This issue is similar to #1636 in which the site added a class when clicking on the element. While that issue was resolved by fixing #1603 this one is not since the site adds a class upon hovering over the element.

Generally, the site shouldn't handle any onmouse* events since the user is interacting with our overlay and not with the site. Therefore I'd suggest catching those events.

  • Platform changed from Opera to Unknown
  • Priority changed from Unknown to P3
  • Ready set

I agree with the suggested solution. Though this means that you can't expand JavaScript menus in order to block elements within those menus anymore. However, this behavior will be less unexpected than the side effects of not catching those events.
