I tried to find something similar in previous materials, it seems like [here](https://github.com/galaxyproject/training-material/blob/d13771e996e13fdc821a28556692a8e4e1675291/topics/single-cell/tutorials/scrna-raceid/tutorial.md?plain=1#L429) someone had the same issue. But there, it is [rendering fine](https://training.galaxyproject.org/training-material/topics/single-cell/tutorials/scrna-raceid/tutorial.html#performing-the-clustering), so maybe this only occurs when running the GTN page in Gitpod?
