Environment

VS Code version: 1.95.2, e8653663e8840adaf45af01eab5c627a5af81807, x64
C# Extension version: v2.55.21

Steps to reproduce

1. Create or open any C# project.
2. Open or create a top-level statements (Program.cs) file.
3. Add the following code:

   int i;
   
   partial class Program;

4. Observe int i; being treated incorrectly; it is "folded away":
   

Expected Behavior

The statement on the first line is not treated incorrectly like this.

Actual Behavior

The statement is in an extra "container", navigating to the line with the cursor hides the cursor behind that container. The contents of the line can still be edited. Clicking the container does not yield a response.
