**To Reproduce**

Steps to reproduce the behavior:

1. Go to Admin console > UI settings and set the value of `Editor page indent type` to `Default, minimal indents`

@fxprunayre any idea about this? I would expect `Default, minimal indents` displays the metadata as used to be displayed in GeoNetwork 3.12.x.

Start in web-ui/src/main/resources/catalog/js/edit/EditorController.js at the referenced lines, then reproduce the issue by setting Admin console > UI settings > Editor page indent type to “Default, minimal indents” and creating a new iso19139 metadata record in the Editor board. Done means the editor uses the selected minimal-indent style instead of colored indents.
