Comment (by laurelfulford):

 [attachment:39035.0.patch] is a first crack at one possible solution: I
 added a JavaScript check to see if `object-fit` is supported, and if it
 is, a CSS class is added that updates the styles to use it.

 One drawback is that it adds a flash of 'incorrect' styles - right now, in
 browsers that support `object-fit` you see a flash of a zoomed image/video
 that then corrects itself. It can be switched the other way, but then
 browsers that don't support `object-fit` (''shakes fist at IE'') will show
 a flash of a pretty broken image/video placement before correcting.
