aria-valuemax and aria-valuemin ambiguity on separator.

[Epigenetic]

Describe the change

The description of the separator role makes it clear that the aria-valuemax and aria-valuemin only have implicit values if the separator is focusable. However, the characteristics table for the role does not indicate this like it does for other characteristics of the role like supported properties and state.
