When I click and drag on the current view in the minimap (i.e. the grey rectangle showing the currently visible portion of the document), the current view jumps so that my cursor is centered in it. I was expecting it to keep my cursor at the same relative location in the current view and just scroll smoothly as I drag. This is particularly noticeable if you click near the top or the bottom of the current view to start your drag.
This seems like a bug to me, but I thought I would post it here first (especially since I don’t have a bugzilla account).
