Use resize-observer-lite fork which uses different strategy

[larsjohnsen]

The scroll strategy which was used does not work when animations are globally disabled, causing media to not flow properly. The other available strategy, object, does not have this issue.

Replaces #4759

@erikdesjardins Can you fork the repo larsjohnsen/resize-observer-lite to the organization, like is done with jquery.tokeninput?

[erikdesjardins]

Done. Everyone in the org should have write access to https://github.com/Reddit-Enhancement-Suite/resize-observer-lite

Another potential option is to change the disableAnimations CSS to avoid applying to the relevant media elements; maybe you've already considered that and discarded it?

[larsjohnsen]

Thanks.

I haven't really explored adding an expectation to the disableAnimations CSS as I am satisfied with just switching the resize detection strategy; there doesn't appear to be any significant performance difference between the two.

[erikdesjardins]

Sounds good to me.
