Where to center to is only one vector, the other is how much to zoom: ideally it’s such that the text block fits on the screen. But again, that requires knowing the bounds of the text block. Zooming by a constant wherever you tap is a much less useful feature for text (vs. a map for instance), but I think it’s what we defaulted to (can’t remember if it was that of just nothing).
