Per spec, you are describing differences in whether the elements "can
be reached using sequential focus navigation". The set of "focusable"
elements includes elements that /cannot/ be reached using sequential
focus navigation.

That is, the spec distinguishes the concept of focusable from the tab
cycle. See especially the normative requirement for negative tabindex:
"The user agent must allow the element to be focused, but should not
allow the element to be reached using sequential focus navigation."

I guess the critical point here is that when an element receives
focus, users must be made aware of what sort of control it is, so
"presentation" makes no sense. So it seems that this wider definition
of "focusable" is more important than the narrow tab cycle sense?
