pixelsToPositionY returns y bigger than maxRows

[ozdavid]

When getting into pixelsToPositionY from calculateItemPosition it sends round method: Math.round(). Therefore pixelsToPositionY returns 2 even though my maxRows is 2 which causes problems with grid colliison. This could have been solved if the round method in pixelsToPositionY would have been Math.floor().
Is there any way to do this?
