 Call Agenda
Hi sorry the Agenda is out so late, as discussed at the Face to Face, in
the future meeting invites will be out earlier but the deadline for marking
items with '/agenda' will be the Thursday (Pacific Time) before.

Whether there will be a WG or CG call will depend on which repos have the
most issues to be discussed.

This agenda can be viewed and updated on Github
<https://github.com/immersive-web/administrivia/blob/master/meetings/wg/2020-02-11-Immersive_Web_Working_Group_Teleconference-agenda.md>
.

If you would like to add an item to the agenda or volunteer to scribe
please open a pull request against this agenda.

   - webxr#956 Visibility state behavior is not clearly specified for
   inline sessions <https://github.com/immersive-web/webxr/issues/956> -
   cabanier

From reading the spec, it is unclear what events should trigger on inline
session. For head mounted devices, should inline session become hidden when
going immersive?


   - webxr#958 Controller and ray position are UA dependent
   <https://github.com/immersive-web/webxr/issues/958> - cabanier

Someone reported an issue on twitter
<https://twitter.com/fernandojsg/status/1225871240243679232> where the
pointing ray was intersecting the model that was posted on the WebXR
profiles repo <https://github.com/immersive-web/webxr-input-profiles>.
