Comment 2

[Emilio Cobos Álvarez (:emilio)]

Attachment: Bug 1736158 - Force light color-scheme for reftests. r=jgraham,mstange

Bug 1529323 changed prefers-color-scheme to follow the Firefox theme. This
means that dev-edition has a dark prefers-color-scheme by default, because it
uses the dark theme.

Reftests rely on light color-schemes among other things because about:blank
draws a dark background when the user prefers a dark color scheme if it has no
opener.
