Just found out the warning appears only in Safari.
Right now, you have to scroll the green window all the way to the farthest edge of the next box to make the snap happen. I'd like to cut that distance in half.
When reading the docs you mentioned, I thought this could be only possible with an array (eg. snapTo: [0, 0.1, 0.5, 0.8, 1]), so I wouldn't be able to use the "labels" value (snapTo: "labels"). Is that correct?
