Wrong rounding pixel to row

Line 170 in b589409

return Math.floor(pixelPosition / this.defaultLineHeight)

My values:

pixelPosition: 959
this.defaultLineHeight: 25.238096237182617
pixelPosition / this.defaultLineHeight: 37.99811170333564
Math.floor(pixelPosition / this.defaultLineHeight): 37

It blocks scrolling in my case. I have custom dpi on screen, that maybe causing issue.

Maybe it would be better to use round instead of floor?
