1711297 - -moz-context-properties:fill no longer works in an extension page

Status: RESOLVED WONTFIX

(Core :: CSS Parsing and Computation, defect)

Description

[clessili]

Attachment: nightly 90 and firefox 88

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0

Steps to reproduce:

My extension replaces the homepage and uses Firefox's icons (chrome://...).
I use the properties -moz-context-properties:fill; along with a fill color to change the color of those icons.

Actual results:

No matter the fill color, the icons stays black, and the inspector tells me the property it is invalid.

Expected results:

The icon should change its color like in Firefox 88.

moz-context properties are supposed to be restricted to mozilla internal extensions only.
