MarkdownTextBlock component cannot function properly when AOT is enabled.

[XTY64XTY]

Describe the bug

When I use code to dynamically create a MarkdownTextBlock, the entire program crashes, and the exception is not caught by the default settings of VS 2026.

When I turn off AOT, the program works normally.

Steps to reproduce

1. Enable AOT in the project
2. Use the MarkdownTextBlock component

Expected behavior

If everything is normal, MarkdownTextBlock should work properly.
