Currently, on the desktop Minerva skin, the mobile editor is loaded. If you somehow cheat and load the desktop VisualEditor instead (e.g. https://gerrit.wikimedia.org/r/470087), it works mostly fine!, but there are a few issues I noticed:
In view mode:
{F26860529}
* Two-tab mode doesn't quite work:
** No secondary tab is inserted at the top of the page, the only tab always opens the source editor
** Secondary section edit links are inserted, but they are indistinguishable from the originals
** Link dividers look weird (huge font size)
In edit mode:
{F26860539}
* There is no button to close the editor without saving changes (same problem as Timeless: T162503, see also: T85470)
* Whole content has additional padding
* Numbers of ordered lists are shown on separate lines
* Top-level heading underlines do not go all the way
* While loading NWE, temporary textarea is super squished
