Hello TAG!

I'm requesting a TAG review of ContentVisibilityAutoStateChanged event.

This proposal is to add an event that would fire on a content-visibility: auto
element when the rendering state of the element changes due to any of the
attributes that make the element relevant to the user.

• Explainer¹ (minimally containing user needs and example code): explainer
• Specification URL: This will be an amendment to css-contain spec. I will update the issue once the spec text is available.
• Security and Privacy self-review²: self-review
• Primary contacts (and their relationship to the specification):
  • Vladimir Levin (@vmpstr, Google)
  • Tab Atkins (@tabatkins, Google)
• Organization(s)/project(s) driving the specification: Google
• Key pieces of existing multi-stakeholder review or discussion of this specification: CSSWG discussion
• External status/issue trackers for this specification (publicly visible, e.g. Chrome Status): https://chromestatus.com/feature/5179553291436032

Further details:

• I have reviewed the TAG's Web Platform Design Principles
• Relevant time constraints or deadlines: None
• The group where the work on this specification is currently being done: CSSWG
• Major unresolved issues with or opposition to this specification: None
• This work is being funded by: Google

We'd prefer the TAG provide feedback as:
