Title: Properly calculate offset of widget from top of virtual scroll area

For #2399. To @gruehle

I was wrong in thinking that the lineSpace actually extends to include the whole virtual scroll area--it's still just part of the mover. We have to calculate the top of the scroll area (excluding padding), as that's what `scrollIntoView()` appears to expect the top coordinate to be relative to.
