I found a bug in the Wikipedia app for Android. If you use the dark mode of the app, the color scheme under pictures is no longer displayed. This is not the case when using the light mode.
There are two screenshots in the appendix that illustrate the problem. This error occurs with all image descriptions.
The user's example is from German wikipedia. I checked this in English and Spanish and it doesn't seem to be happening there. Is this something unique to de.wiki?
