The "projects" view in the designer has black on dark grey text

The designer changes the background colours to a dark scheme, no matter what theme the user has selected. That is questionable in the first place. It also doesn't change the foreground colour of the "projects" view in the sidebar, though (in contrast to e.g the file system view). This makes the projects view very hard to read, at least in "flat" theme, which has a white background by default.
