Joanie, without a widget role, there's no way to distinguish between an interactive separator where keys must be passed through and a horizontal rule.

This is just like the difference between a table and a grid or a tree and a list.

And, as in those other cases, there are many side effects of attempting to use a property to distinguish between a widget and a structure. That Is why we added the table role instead of adding something like aria-interactive=false to grid.

In the message below, I mean the addition of a *splitter* role.
Apologies for the noise/spam.
