Docs: Markdown inline code selector should be RichSpan.code, not RichRun.code

[TomOSullivan]

Describe the bug

Summary

The Markdown styling documentation
instructs users to style inline code spans with the selector RichRun.code. In the
shipping control, the code class is applied to a RichSpan, not a RichRun, so
the documented RichRun.code selector matches no elements and has no effect.

The working selector is RichSpan.code.

Environment

• Avalonia.Controls.Markdown 12.1.2
• Avalonia 12.0.3
• OS: Windows
• Docs page last updated: May 14, 2026

Where the docs say RichRun.code

Two places on the styling page:

1. Available selectors table:

   RichRun.code — Inline code spans. Background and monospace font.

2. Custom styling example:

   <Style Selector="RichRun.code">
       <Setter Property="Background" Value="#e8f0fe" />
       <Setter Property="FontFamily" Value="Cascadia Code" />
   </Style>
   
   

To Reproduce

<Style Selector="RichRun.code">
    <Setter Property="Background" Value="#e8f0fe" />
    <Setter Property="FontFamily" Value="Cascadia Code" />
</Style>

Expected behavior

Expected vs. Actual
Expected: Following the docs, Style Selector="RichRun.code" styles inline code spans.
Actual: The selector matches zero elements. Inline code retains its default
appearance. Switching the selector to RichSpan.code works immediately.

Additional context

Suggested fix
Update the selector table entry and the custom-styling example from RichRun.code to
RichSpan.code:

It seems that the issue I reported is related to this one.

Yes, the default template is already fixed. Only the documentation needs some adjustment.
