CSS variable `--color-icon-tertiary` and more are gone 😩 #4855

Please ensure:

• The bug is caused by Refined GitHub. It doesn't happen if I disable the extension.

Description

Particularly noticeable in dark mode since our defaults are quite bright sometimes.

For example the author border and conflict marker should not be so bright here:
