A couple of issues with the carousel in file view using a mobile device

Please could you let me know which device? Also, is this only happening on Edge?

iPhone, latest IOS. Happening on Safari too:

This file has 4 screenshots. 

This is potentially happening due to lazy loading (which only loads images when they're in/near the viewport). When the images are in a carousel, they're considered offscreen until they're scrolled to, but maybe iOS isn't seeing any of those images at all until the page is scrolled.

I've just pushed an attempted fix, which involves adding the width and height attributes to the images. This will reserve space for them and give the browser a better idea on where they'll appear in the viewport before they've loaded. If this doesn't fix the issue in the next update, let me know.
