Why there is no highlight in tsx code when uses @rspress/plugin-preview?

[PuffMeow]

I add the plugin of @rspress/plugin-preview. Then I use code to import my tsx demo component, there is no highlight.
Like this:
<code src="./Demo.tsx" />

Currently rspress only supports highlighting of code using syntax like below

```tsx

Is there any plans to support it?

You can make an issue with PR Welcome labeled to help us tracking on it, I think it should be supported but maybe not ASAP as you expected.
