[csswg-drafts] Question and suggestion about paused property value (#13434)

DevSDK has just created a new issue for https://github.com/w3c/csswg-drafts:

== Question and suggestion about paused property value ==
> Hi and thank you for the draft of spec :)
> 
> I have a question and a minor suggestion.
> 
> What is the expected behavior for `paused`?
> 
> The current version of the specification simply describes it as a "static image." It is unclear whether this implies rendering a specific frame (e.g., the first frame) or freezing the animation at the current timestamp.
> 
> If this is intended to be user agent dependent or to render the first frame, how about renaming it to `none` or `stopped`
> 
> If the expectation is to stop the moment at the current frame, I think it would be good to clarify this. I.e., `animation-play-state` in css animation.
> 
> According to the [Possible Extensions](https://github.com/webplatformco/project-image-animation/tree/main/image-animation-property#possible-extensions) on the Explainer,
> 
> `paused [ first | last | last-shown | <time> | <percent> | <number> ] ?`
> 
> We can adopt:
> 
> `stopped [ first | last | <time> | <percent> | <number> ] ?` - `first` is default case.
> 
> and separated the value for `last-shown` to `paused`.
> 
> From a Chromium implementer's perspective, `none` or `stopped` (resetting to the first frame) is significantly easier to implement than pausing at the current frame.
> 
> If support for "freezing at the current frame" is planned for the future but not immediately required, adopting none or stopped first might be a better choice for a minimal viable version of the standard.
