In the current vector-2022, the ToC does not appear during Preview, if I'm using the standard wikitext editor. (i.e. not using the beta-feature "New wikitext mode").
This makes it impossible for me to understand what results my edit will have, until after I Publish it.
- As an editor who is trying to improve the 'structure' of a page, by adding/editing/refactoring/sorting of the ==Headers== and sub-headers.
- I want to be able to Preview my changes without saving the page.
E.g. If I add the wrong quantity of === on either side of a heading, I can normally detect this during Preview.
