1821269 - :nth-child(... of class) within shadow root reftests don't call declarative shadow DOM polyfill

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement)

Description

[Zach Hoffman [:zrhoffman]]

Although the reftests load the polyfill, they don't call it, which would keep those reftests from passing once invalidation for :nth-child(An+B of <selector list>) within shadow root is otherwise working (bug 1818154).

Attachment: Bug 1821269 - Use declarative shadow DOM polyfill for :nth-child(... of <selector>) in shadow root reftest r?#style,#layout

Although the polyfill script was already included, it was not called
(and we still need it until bug 1712140 is resolved).
