Rename crashes with source generated partial method signatures

[severity:It bothers me. A fix would be nice]
I have a logging class that uses source generators to help with logging Api calls: `internal static partial class ApiLogger`. This class has a number of methods that are defined for example like this:
```C#
[LoggerMessage(
Message = "Api {httpMethod} {methodName}. User: {principal}. Parameters: {parametersJson}.",
Level = LogLevel.Information
)]
internal static partial void LogApiCallWithParameters(this ILogger logger,
HttpMethod httpMethod,
string methodName,
PrincipalLogFormatter principal,
string parametersJson
);
```

If using rename command on one of the parameters, VS will give an error "Feature 'Rename' is currently unavailable due to an internal error." and a stack trace:
```
StreamJsonRpc.RemoteInvocationException: The given key 'SourceFile(C:\my-project\obj\Debug\net8.0\Microsoft.Gen.Logging\Microsoft.Gen.Logging.LoggingGenerator\Logging.g.cs[5972..5983))' was not present in the dictionary.

```

I'd guess it's a common problem when using automated features with source generation.
