EditorConfig naming rule for test classes is ignored, but works for methods.

I'm trying to add underscore delimiter as an allowed word delimiter in a C# project within a solution.
It's only supposed to be allowed in the test project.

But I can't manage to make R# not complain about the class name.

My root file has a general pascal case rule for all identifiers and an overriding one for private fields:

[*.cs]

dotnet_naming_rule.identifiers_should_be_pascal_case.severity = suggestion
dotnet_naming_rule.identifiers_should_be_pascal_case.symbols = identifiers_pascal_case
dotnet_naming_rule.identifiers_should_be_pascal_case.style = pascal_case

dotnet_naming_symbols.identifiers_pascal_case.applicable_kinds = namespace, class, struct, interface, enum, property, method, field, event, delegate
dotnet_naming_symbols.identifiers_pascal_case.applicable_accessibilities = public, internal, private, protected, protected_internal, private_protected
dotnet_naming_symbols.identifiers_pascal_case.required_modifiers =

dotnet_naming_style.pascal_case.required_prefix =
dotnet_naming_style.pascal_case.required_suffix =
dotnet_naming_style.pascal_case.word_separator =
dotnet_naming_style.pascal_case.capitalization = pascal_case

The test project allows underscore for class, test_type and method:

[*.cs]

# Allow underscores in test classes & methods
dotnet_naming_rule.tests_allow_underscores.symbols = test_members
dotnet_naming_rule.tests_allow_underscores.style = pascal_with_underscores
dotnet_naming_rule.tests_allow_underscores.severity = suggestion
resharper_csharp_naming_rule.tests_allow_underscores = AaBb,AaBb_AaBb

dotnet_naming_symbols.test_members.resharper_applicable_kinds = method,class,test_type
dotnet_naming_symbols.test_members.applicable_kinds = method,class
dotnet_naming_symbols.test_members.applicable_accessibilities = *
dotnet_naming_symbols.test_members.required_modifiers =

dotnet_naming_style.pascal_with_underscores.capitalization = pascal_case
dotnet_naming_style.pascal_with_underscores.word_separator = _
dotnet_naming_style.pascal_with_underscores.resharper_style = AaBb,AaBb_AaBb

It seems to work for methods, but no matter what I try, I can't manage to remove the green squiggly under test class names.
The rule indicated by the lightbulb action menu is `identifiers_should_be_pascal_case`.

What am I missing?
