Fix compiling styles with individual SCSS for dark mode

The variable was not properly cleared after using including the contents within
the SCSS and then was attempted to be parsed as an SCSS value to provide it as
a SCSS variable.

Introduced in ba7168323f6632361b694d7eb2c09439902fe447.

Fixes #5398
