----------------------------+-----------------------------
 Video thumbnail images on pages like https://wordpress.tv/ and
 https://wordpress.tv/category/year/2017/ (excluding video in the 'player'
 element) should be loaded more efficiently.

 Specifically:
 - The thumbnail should be generated/requested at an appropriate size
 (160x100)*
 - A `loading="lazy"` property should be added.
 - Explicit `height` and `width` properties should be added.
 - If available, an `srcset` property should reference a `x2` size option
 (at 320x200).



 *E.g., https://videos.files.wordpress.com/bjn9Fo1g/video-
 33873a5e9c_mp4.scrubthumb.jpg, which is currently on the homepage, is
 loaded at 1920x1080, but squashed into a 160x100 space
