amp-lightbox-gallery: issue when only 2 images

[javierparis]

When triggering an amp-lightbox-gallery that only has 2 images, it's not possible to swipe to the right, and swiping to the left has a flickering effect and it's not consistently displaying the image

How to reproduce it:
Go to the playground for amp-lightbox-gallery
https://playground.amp.dev/?url=https%3A%2F%2Fpreview.amp.dev%2Fdocumentation%2Fexamples%2Fcomponents%2Famp-lightbox-gallery&mode=Galaxy+S5
and leave only 2 images, something like this:

<div>
    <amp-img lightbox src="https://preview.amp.dev/static/samples/img/road-1.jpg" width="300" height="200" layout="responsive"></amp-img>
    <p class="paragraph">Lorem ....</p>
    <amp-img lightbox src="https://preview.amp.dev/static/samples/img/road-2.jpg" width="300" height="200" layout="responsive"></amp-img>
    <p class="paragraph">Lorem ....</p>
  </div>

Reproduce it using Google Chrome tools, trigger the device toolbar, and choose iphone 6/7/8 for instance. Arrows seem to work though

I think we should wait for the switch to use <amp-base-carousel> in lightbox (#21568) for this one. I tried this by enabling the 'amp-base-carousel-lightbox and layers experiments and it works correctly. Currently, it tries to loop for two slides, which can be weird, but the change to disable looping for two slides should go live soon.

Here is what we still need to launch this: #21568 (comment)
