Although this a change request, as the context menu currently only offers this functionality for a few defined types of elements like images, I accept this to get an official decision on whether this makes sense as compared to the functionality offered via the bubble ui.

The "Block Element" context menu entry is only created for <img>, <video> and <audio> elements. That makes sense for following reasons:

1. Those are the only elements that have a mandatory src attribute. So we can always generate a filter for them. Otherwise we would have to determine whether we can generate a filter for the element and update the context menu accordingly every time the user moves the mouse.

2. In most other cases it wouldn't be clear which element is going to be blocked (the leaf node or any of its ancestors). However, this is obvious when using "Block Element" from the bubble because it highlights the element.
