1956140 - Implement active-view-transition pseudo class

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement)

Description

[Boris Chiou [:boris]]

The :active-view-transition pseudo-class applies to the root element of the document, if it has an active view transition.

This looks like a simple bug I think because it just needs to check if the root element has the active view transition, and then apply the rules.
