[webkit-dev] [Intersection Observer] Accept a Document as an explicit root

[Frédéric Wang]

Hello,

This email is to announce that Igalia has started to implement a recent
enhancement to Intersection Observer, that allows users to specify a
Document as an explicit root. The typical use case is when such a
Document is the one of an iframe. Below is some documentation:
