IDE0021 showing up as warning despite being silent in editorconfig

**Version Used**:
Visual Studio 17.13.0 Preview 1.0 and .Net 8.0.206

**Steps to Reproduce**:
Clone https://github.com/logankp/AnalyzerBug and open Class1.cs in Visual Studio or VS Code. Observe the constructor being underlined in yellow squiggles and showing up as a warning.

**Diagnostic Id**:

IDE0021: Use expression body for constructor

**Expected Behavior**:
IDE0021 should not show up as a warning.
**Actual Behavior**:
IDE0021 is showing up as a warning.

I have this configured in `.editorconfig` as such:
```
[*.cs]

csharp_style_expression_bodied_constructors = true:silent
```

Reproduce with the linked AnalyzerBug repository by opening Class1.cs in Visual Studio or VS Code, then inspect its .editorconfig and the IDE0021 diagnostic. Compare the configured silent severity with the warning shown; done means IDE0021 no longer appears as a warning under this configuration.
