and then over me (this is anonymous content).

In the first block none of the elements is inside anonymous content.
In the second one the <div> which handles the (light green) :hover state and the latter <span> element are inside anonymous content.

Move the mouse over me (this is normal content) and then over me (this is normal content).
Move the mouse over me (this is normal content)

The question is, should both cases work in the same way?
