can't bind to `open` attribute on `<details>` or `<dialog>` elements

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

cannot bind to open attribute
```razor

Summary

expanded text

@code {
public bool IsOpen { get; set; }
}
```

or

```razor

content

@code {
public bool IsOpen { get; set; }
}
```

### Expected Behavior

for this to work, and for any html attribute to be bindable, rather than a list of:
- value
- checked
- others

I can't seem to find a list of the supported bindable attributes or events in the documentation either

### Steps To Reproduce

_No response_

### Exceptions (if any)

_No response_

### .NET Version

9.0.304

### Anything else?

_No response_

Start from the two Razor reproductions using @bind-open on and , and identify how supported bindable attributes and events are documented or handled. Done means the requested binding behavior is defined and implemented, or the supported-attributes limitation is clearly documented with guidance for these elements.
