David: Is this intended for user agents or site owners?
Niklas: UA have to implement the media queries. Site authors
can write appropriate code.
David: Is this already available in user agents?
Niklas: Yes, but only with polyfills and a workaround for
environment variables.
David: This is good for the work of the personalization tf.

<joconnor> Nice presentation 🙂

David: Are there negative side effects of the hack?
Niklas: In the draft for environment variables, there is a note
that this is an open issue. But no negative side effects.
<Fredrik> Great presentation, Niklas! Very interesting.

Michael: Looks like a straight forward recharter. No major
changes.
Becky: Looked at PiP.
Michael: We had only comments on EME (Encrypted Media
Extensions).
… It is an approach to digital rights management
<Fredrik> Thanks - was also wondering.
John: Very political discussion on EME

Michael: This allows us to track existing issues that are filed
on specs.
… Now added: When a spec is going to wide review, we can flag
issues or close issues.
Becky: This is similar to the process for i18n.

Michael: We had a discussion on this about 1 year ago.
… No actions since then i believe.
… It is an API for an image. Like an abstract class for images.
Becky: "Label" provides the accessible name.
John: Specify alternative images based on size. But only one
alternative text can be provided.
Michael: It is probably meant for icon collections.
Janina: Yes. And it should be made clear.
Michael: Either file a comment or stop our tracking?
John: Let me investigate this and discuss again next week.
