Summary:

caretRangeFromPoint is a non-standard API for obtaining a Range object (node and position within node) from pixel coordinates, similar to caretPositionFromPoint. It has been available in Blink/WebKit since 2010, and recently there has been an attempt to standardize it. The web-platform-tests have already been accepted.

Implementing caretRangeFromPoint allows us to fix caretPositionFromPoint’s shadow DOM behavior without introducing regressions, as discussed here: https://bugzilla.mozilla.org/show_bug.cgi?id=1927838.
