<div>
<pre>When we have scroll-snap point markup that specifies a horizontal snap range, but not a vertical, we get a default value of "{0, 15}".
Example:
.horizontalGallery {
width: 300px;
height: 300px;
overflow-y: hidden;
overflow-x: auto;
-webkit-overflow-scrolling: touch;
-webkit-scroll-snap-points-x: repeat(100%);
-webkit-scroll-snap-type: mandatory;
}
This produces snap points as follows:
horizontal = { 0, 300, 600, 900, 1200, 1500 }, vertical = { 0, 15 }
I would expect to see either no snap points, or snap points for the two scroll extrema (i.e., vertical = { 0, 1500 }</pre>
