When editing complex yaml files, like https://raw.githubusercontent.com/argoproj/argo-helm/main/charts/argo-cd/values.yaml, which have deep levels and lots of comments, folding does not work correctly.
If you also open treemacs view, the nodes listed in treemcs view are correct. So I think yamlls can respond the node information correctly, but origami could not figure out which lines it should hide/show.
Not sure it is an issue in LSP or origami.
