Description

In Legacy Vector the table of contents is automatically hidden on pages with less than 4 sections. There is not much documentation regarding the reasoning behind this decision. From Help:Section:

For each page with at least four headings, a table of contents (TOC) is automatically generated from the section headings unless...

(The conversation on Help talk:Section unfortunately hasn't yielded much yet)

While on some (maybe most) pages with less than 4 sections the table of contents might not add much value, on some pages it will. Additionally by showing it we get the benefit of a consistent layout for all article pages. This will remove any confusion regarding why it's shown on some pages and not on others, as well as prevent the page content from shifting when switching from a page with a table of contents to a page without one (or vice versa).

Demo

Here are a few examples of articles with less than 4 sections, with the table of contents showing:

3 sections
https://di-collapsible-menus.web.app/Johnny_Miqueiro
https://di-collapsible-menus.web.app/Hurkett
https://di-collapsible-menus.web.app/Polycystine

2 sections
https://di-collapsible-menus.web.app/Yusuke_Yachi
https://di-collapsible-menus.web.app/Henning_Elbirk
https://di-collapsible-menus.web.app/Norway_Ski_Club

1 section
https://di-collapsible-menus.web.app/Rhytiphora_vicaria
https://di-collapsible-menus.web.app/Hecyra_marmorata
https://di-collapsible-menus.web.app/Freedom_List

This is a prototype but hopefully close enough to the real thing for us to get a sense. What do people think?
