(Whiteboard: [addons-jira])

As part of Bug 2001318 we are planning to start the deprecation of the CSS filter being implicitly applied on SVG page icons when the browser UI is in dark mode (e.g. when a custom dark theme is enabled or when the system in dark mode and a dark mode theme automatically selected), starting from disabling that implicit behavior in nightly build only.

This followup bug is tracking letting the restriction to ride the release train (after we have documented and communicated the expected change in behavior and how extensions can create SVG icons that will be adapting to dark/light themes using the prefer-colors-scheme media queries and left a few cycles per deprecation policy).
