See the following example where there is a large overflowing image:
https://snap.glitch.me/carousel.html

Note that this example uses "center" alignment snapping.

It works as expected with small scroller sizes but once scroller size
is larger than a certain size but still smaller than the image then it will snap.

My guess is that we are triggering the condition where the previous and next snap points are smaller than the snapport size.

In particular, since this example is using center aligned snapping, the
distance between the snap position for the larger item to the next item only includes half the size of the actual item. This can explain why we
do the right thing for smaller viewports but not for larger ones.
