- Open revisionslider on https://www.wikidata.org/w/index.php?diff=607185200&oldid=607185151
- Klick Button "> (see newer revision)"
- Revisionslider scrolles on full circle to the right
- The knobs of the sliders are outside of the slider
If you then move the blue knob to another revision and go back to the previous view it will look even weirder.
