Dragging text upwards triggers scrolling far too early

[proimage]

Type: Bug

1. Create a document with multiple screens of text (one way is to set to HTML, then use Emmet to auto-complete lorem*60 or so).
2. Scroll down to the middle-ish, so there's plenty to vertically scroll in either direction.
3. Select a bit of text.
4. Click and hold in the selection to drag that text downwards, and once you get near the bottom edge (90-95% of the way there?), the document should scroll a few lines each time there's mouse movement. This is the normal, expected behavior.
5. Now drag upwards. Instead of scrolling being triggered near the top edge, it gets triggered at around the vertical halfway point. This is the bug.
