Code Block Syntax highlighter

[codeaphex]

There seems to be an issue with the code block syntax highlighter.
For example this markdown:

```EditorConfig
[*.{cs,vb}]
dotnet_naming_rule.private_members_with_underscore.symbols  = private_fields
dotnet_naming_rule.private_members_with_underscore.style    = prefix_underscore
dotnet_naming_rule.private_members_with_underscore.severity = suggestion

dotnet_naming_symbols.private_fields.applicable_kinds           = field
dotnet_naming_symbols.private_fields.applicable_accessibilities = private

dotnet_naming_style.prefix_underscore.capitalization = camel_case
dotnet_naming_style.prefix_underscore.required_prefix = _
```

Renders like this...
in a GitHub Issue:

and like this in Markdown Preview:

If I change the Language Tag from EditorConfig to INI it shows some highlighting though

Are you using a different highlighter than GitHub or is this the default Markdown syntax style?
GitHub is using Linguist according to this page https://docs.github.com/en/free-pro-team@latest/github/writing-on-github/creating-and-highlighting-code-blocks#syntax-highlighting

It looks a bit better now but in all honesty highlight.js and linguist are not 1-1
