 > Intersection Observer API

 Also, this is being used extensively in the [https://wordpress.org/plugins
 /optimization-detective/ Optimization Detective] plugin (with its
 extensions [https://wordpress.org/plugins/image-prioritizer/ Image
 Prioritizer] and [https://wordpress.org/plugins/embed-optimizer/ Embed
 Optimizer]). These are feature plugins intended for eventual proposal for
 core merge.

 The Performance [https://github.com/WordPress/performance/issues/1308
 issue] for `content-visibility` is also for Optimization Detective.
