:emilio, since you are the author of the regressor, bug 1840480, could you take a look? Also, could you set the severity field?

For more information, please visit BugBot documentation.

Yeah so this library is using a different codepath for animations based on CSS.registerProperty presence, and we still haven't implemented interpolation of typed custom properties. Filed a bug for that.

Hello everyone!

Could someone kindly assist in deciphering the severity and priority codes, namely "Severity: S3, Priority: P3," and provide an ETA, even if it's approximate, for actual appearance in users' browsers?

I need this for a small feature and would like to understand if I need to go with JS fallback or if this will be fixed earlier than we do a release.
