[Bug] docfx metadata appears to be broken with 9.0.200

**Describe the bug**
After updating to the lates version of the sdk `docfx metadata .\docfx.json`. The failures seem to be related to blazor framework libraries.

**To Reproduce**
Steps to reproduce the behavior:
1. Run `docfx metadata .\docfx.json` in on metadat project that previously worked.

```
error: D:\source\MyWeb.Ui\Components\Help\HelpLinksComponent.razor.cs(46,32): error CS0115: 'HelpLinksComponent.SetParametersAsync(ParameterView)': no suitable method found to override
```

**Expected behavior**
Metadata generation should resolve blazor base classes.

**Context (please complete the following information):**
- OS: Windows 11
- Docfx version: 2.78.2+3ff9ae7a9700029e0023a7ece18a723d351f1e9b
