Issue #12344
**Bug**
Current colorization rules are too relaxed. Links inside lists of block quotes for example end up getting colored differently than normal links.
**Fix**
- Add a scope to the textmate markdown grammar so that we can identify the symbol that starts a list or quote.
- Remove text colorization rule for lists and quotes since this just duplicates the normal text color.
- Only apply special puctuator colorization to the start symbol for lists and quotes
Issue #8264
**Bug**

Issue #7725
Nested html is not colorized properly for markdown:
```md
<div class="custom-class" markdown="1">
<div>
nested div
</div>
</div>
```
**Fix**
According to the commonmark spec, general html blocks end with a blank line: http://spec.commonmark.org/0.25/#html-blocks
This change relaxes the while so that we only check for blanklines, instead of trying to match the start tag (which fails when nesting elements)
Issue #8636
**Bug**
Fenced code block closing tags break colorization if they are prefixed with spaces. According to the commonmark spec, up to three spaces are allowed.
**Fix**
Update defintion of fenced code block closing tag to support spaces.
Closes#8636
Issue #12289
**Bug**
Html tags prefixed by 1 to 4 spaces are not colorized properly
**Fix**
Consume optional leading whitespace when matching html tags instead of only starting from previous match location
closes#12289
Adds c# to the list of language highlighted in markdown fenced code blocks. You must have a c# language extension install for this to work.
Closes#7003
**Bug**
In Markdown preview, code blocks in headers are the wrong font size.
**Fix**
Specify that code blocks in headers should inherit their font-size, instead of brining their own.
Issue #7638
**Bug**
Open a `.txt` file containing markdown in VSCode. Select the editor language as `markdown` and the highlighing kicks in, but there is no preview button for the file.
**Fix**
Base display of the markdown preview button on `resourceScheme` instead of `resourceLangId`.
