GetAnalyzerOptions is not being called in SourceGeneratorTest

[kzrnm]

In Microsoft.CodeAnalysis.CSharp.SourceGenerators.Testing 1.1.1, I used the following code:

public class CSharpIncrementalGeneratorTest<TIncrementalGenerator> : SourceGeneratorTest<DefaultVerifier>
    where TIncrementalGenerator : IIncrementalGenerator, new()
{
    public CSharpCompilationOptions CompilationOptions { get; set; } = new(OutputKind.DynamicallyLinkedLibrary);
    protected override CompilationOptions CreateCompilationOptions() => CompilationOptions;
    public CSharpParseOptions ParseOptions { get; set; } = new(languageVersion: LanguageVersion.CSharp9, kind: SourceCodeKind.Regular, documentationMode: DocumentationMode.Parse);
    protected override ParseOptions CreateParseOptions() => ParseOptions;
    public AnalyzerConfigOptionsProvider AnalyzerConfigOptionsProvider { get; set; }

    protected override string DefaultFileExt => "cs";
    public override string Language => LanguageNames.CSharp;
    protected override IEnumerable<ISourceGenerator> GetSourceGenerators() => new[] { new TIncrementalGenerator().AsSourceGenerator() };
    protected override GeneratorDriver CreateGeneratorDriver(Project project, ImmutableArray<ISourceGenerator> sourceGenerators)
        => CSharpGeneratorDriver.Create(
            sourceGenerators,
            project.AnalyzerOptions.AdditionalFiles,
            (CSharpParseOptions)project.ParseOptions!,
            AnalyzerConfigOptionsProvider ?? project.AnalyzerOptions.AnalyzerConfigOptionsProvider);
}

In Microsoft.CodeAnalysis.CSharp.SourceGenerators.Testing 1.1.2, the CreateGeneratorDriver method has been removed, so I modified the code to use GetAnalyzerOptions instead:

public class CSharpIncrementalGeneratorTest<TGenerator> : SourceGeneratorTest<DefaultVerifier>
{
    public CSharpCompilationOptions CompilationOptions { get; set; } = new(OutputKind.DynamicallyLinkedLibrary);
    protected override CompilationOptions CreateCompilationOptions() => CompilationOptions;
    public CSharpParseOptions ParseOptions { get; set; } = new(languageVersion: LanguageVersion.CSharp9, kind: SourceCodeKind.Regular, documentationMode: DocumentationMode.Parse);
    protected override ParseOptions CreateParseOptions() => ParseOptions;
    public AnalyzerConfigOptionsProvider AnalyzerConfigOptionsProvider { get; set; }

    protected override string DefaultFileExt => "cs";
    public override string Language => LanguageNames.CSharp;
    protected override IEnumerable<Type> GetSourceGenerators() => [typeof(TGenerator)];
    protected override AnalyzerOptions GetAnalyzerOptions(Project project)
    {
        var baseOptions = base.GetAnalyzerOptions(project);
        return AnalyzerConfigOptionsProvider switch
        {
            null => baseOptions,
            _ => new AnalyzerOptions(baseOptions.AdditionalFiles, AnalyzerConfigOptionsProvider),
        };
    }
}

However, it seems that GetAnalyzerOptions is not being called. Is there any workaround?
