/**
|
||||
* Table of contents widget
|
||||
* (c) Antonio Tejada 2022
|
||||
*
|
||||
* By design, there's no support for nonsensical or malformed constructs:
|
||||
* - headings inside elements (e.g. Trilium allows headings inside tables, but
|
||||
* not inside lists)
|
||||
* - nested headings when using raw HTML <H2><H3></H3></H2>
|
||||
* - malformed headings when using raw HTML <H2></H3></H2><H3>
|
||||
* - etc.
|
||||
*
|
||||
* In those cases, the generated TOC may be incorrect, or the navigation may lead
|
||||
* to the wrong heading (although what "right" means in those cases is not
|
||||
* clear), but it won't crash.
