Dial jumping

[clemofi]

If I change the dial interaction parameter to vertical and move the mouse fast while dragging, the value of the dial sometimes jumps to 0 or to 1 (depending on the value before). It seems that this is caused by the if statement in line 248 in dial.js which is of course needed for the radial interaction but (as far as i can see) is not necessary in vertical or horizontal interaction mode.
A fix could be to add something like && this.interaction === 'radial'

Thank you! I think you are exactly right. Will aim to add your suggestion in the next round of updates.
