[amp-base-carousel:1.0] amp-base-carousel prevents touchmove vertical scroll even with orientation=horizontal set

### Description

The amp-base-carousel component prevents the vertical scroll touchmove scroll gesture to propagate.

This is not ideal because users would not be able to scroll the page vertically if the gesture started from a component part of the amp-base-carousel structure.

### Reproduction Steps

- browse any amp-base-carousel 1.0 example in Bento or AMP mode
- try to scroll vertically on the page by touching the image.

- expected: the page would scroll
- result: the page doesn't scroll. I guess there is a too strong preventDefault applied on events here.
