[FIX] website: consume padding adjust tour step on mousedown

Before this commit the step about the slider to adjust the padding was
only consumed on click, which does not happen if the slider is used in a
drag'n'drop operation as expected.

After this commit this step is consumed on mousedown so that the
drag'n'drop operation is also taken into account.
