Fix T97518: All buttons with eyedropper highlight if one is hovered

Issue is that the operator acts on the active button, and also uses that in the
poll. So the actually active button would affect the poll of a different
button. For the superimposed icons we need to be able to execute these polls
properly for non-active buttons.

This enables temporarily overriding the active button for lookups via context.
While a bit of a hack it makes sense conceptually.
