Minimap section headers are not shown for regions in HTML and CSS

[Chrysaloid]

Type: Bug

1. Open any .html or .css file.
2. Type a comment: in .html

   <!-- #region Test -->
   <!-- #endregion -->

   or in .css:

   /* #region Test */
   /* #endregion */

3. Look at the minimap and see that there is no "Test" section header displayed.

I have tried different layouts: HTML

<!--
    #region Test 1
-->
<!-- #endregion -->

<!-- #region Test 2
-->
<!-- #endregion -->

<!--
    #region Test 3 -->
<!-- #endregion -->

<!--
    // #region Test 4
-->
<!-- #endregion -->

<!--
    //#region Test 5
-->
<!-- #endregion -->

CSS

/*
  #region Test 1
*/
/* #endregion */

/* #region Test 2
*/
/* #endregion */

/*
  #region Test 3 */
/* #endregion */

/*
    // #region Test 4
*/
/* #endregion */

/*
    //#region Test 5
*/
/* #endregion */

None of them work.

In both HTML and CSS comments 1-3 produce foldable regions and 4-5 don't produce foldable regions.

In JS though, line comments like // #region <NAME> produce section headers correctly.

For now I have figured a workaround for this by using MARK::

<!-- #region MARK: Test -->
<!-- #endregion -->

/* #region MARK: Test */
/* #endregion */

which does produce section header in the minimap, but it also includes the ending comment part so the resulting header is Test --> (or Test */). Not ideal but works for now.

The current implementation uses the folding rules of the outer language for the entire file https://github.com/microsoft/vscode/blob/4af0c6a8f4e8b7ba223d27acd2d894a76a912a5e/src/vs/editor/contrib/sectionHeaders/browser/sectionHeaders.ts#L108-L110 , so in HTML , the following markers will be searched for https://github.com/microsoft/vscode/blob/4af0c6a8f4e8b7ba223d27acd2d894a76a912a5e/extensions/html/language-configuration.json#L28-L33

It would be better to support embed language regions in minimap. The most useful case is in .vue file's <script> section when using composition api

[ICF-M78]

I am a developer of vue. I really can't use tags in vue, but it can be used normally in .ts. Because the combination API can easily cause confusion in the code structure, I need this function more.

Multi-line comments in pure JavaScript using /* ... */ are also not recognized.

Seems the feature is very limited as of right now, at least out-of-the-box. Bit of a shame, especially larger CSS files could benefit so much from proper region & mark support.
