Title: Fixed horizontal scroll step width when MouseEmulation is active

Updated the MWheelHandling mixin to use the "scrollBy" method for horizontal scrolling when the MouseEmulation is active, instead of the "scrollBySteps".

Looks like a copy&paste error for the x-coordinate, the handling for the y-coordinate is correct.
