Re: [w3ctag/design-reviews] Other Spec Review: CSS Image Animation (Issue #1237)

> We have unanswered concerns about doing things like changing focusability via CSS; it is likely to be a potential footgun. Specifically in this case, we (and the explainer) would benefit from answers to some immediate practical concerns like: how will the animated image be named? Where will it get its accessible name from?

This is indeed a tricky area. For now, the `controls` feature considered by explainer is not included in the spec, in large part due to these concerns about automagic focusability, and we went with the `:animated-image` pseudo class instead (at least for now).

Naturally, as authors build controls themselves for the animation, they need to design those correctly in terms of focusability (and every other aspect of making the page accessible). The downside being that it's on them, the upside being that they can do the right thing for the right situation.

The spec does include an explicit reminder to authors about this.
