[macros] typeDeclarationOf returns different results when running in test mode for enums

DefinitionBuilder.typeDeclarationOf returns different results when running in test mode for enums

Repro

https://github.com/cedvdb/sdk/tree/enum_macro_diagnostic

In this repo I modified the original json codable file (json.dart) with the following

    if (type.identifier.name == 'EnumField') {
      builder.report(Diagnostic(
        DiagnosticMessage(
            '${type.identifier.name} is enum ${declaration is EnumDeclaration}'),
        Severity.info));
    }

To have a diagnostic on whether or not a field declaration was an EnumDeclaration . The result is different in the analyzer and during test:

I also tried to add a minimal repro with the files enum_codable.dart and enum_test.dart but those may be slightly bugged, still it demonstrates the same output difference.

Summary: typeDeclarationOf yields inconsistent results for enums when comparing analyzer and test runtime outputs. A reproduction demonstrates this discrepancy using a modified JSON codable file and added diagnostics.
