@mojoaxel Are you not authorized to merge even small PRs that you've created? Who else is supposed to review them?

I don't want to merge my own PRs without an external review. But I think in this case I can ,-)

This PR broke the preview images on the timeline-examples page. 😞 (I fixed it with #2050).
@controversial That's exactly why I want reviews...
