Call Hierarchy view sometimes highlights inside the peek (if open)

[eamodio]

Issue Type: Bug

I haven't yet figured out the steps to get this to happen, but sometimes instead of highlighting in the main editor, the Call Hierarchy view highlights in the peek (assuming it is open).

So it looks like this might be expected behavior (though a bit odd?). So it only happens when focus is inside the peek.

Yeah - it always (and only) shows highlights in the active editor and peek'ed editors are equal in that respect. I don't wanna go down the route of showing it in all visible editors but we can try only showing it in "real" editors. Tho that would mean highlight hide when peeking at something.
