What's the meaning of access modifier for interface (abstract) members?

[Xiao-0x41]

I know, after c#8.0, access modifier can be used for interface default implementation,but the doc says:

Interface members without an implementation (abstract members) are implicitly public and can't have any other access modifier

But I find that the code below is valid in .net10:

public interface IInterface
{
    protected internal void ProtectedInternalMethod();
    internal void InternalMethod();
}

So, what's the meaning of access modifier for interface abstract members? When does it implemented in c#? Is it merged into ECMA Spec?

The documentation looks incorrect. The access modifiers are valid and functional: https://sharplab.io/#v2:C4LglgNgNAJiDUAfAAgZgARgHbAKYCcAzAQwGNd0BJSnAk8gWACgBvZ9D9AB3wHs9SeGJlr4sxCOmQAWdAAU+AoTTxiJAWVzAAFrxgAKAJQBudp2yrxkmVVFXNOvUdNNO3fGABuxPO/65BXGEbB10DE2YAX2ZmZAAmdABhZjZXThD9alF6CjBDMw5UtzcwADpQpwi0jmimSKA===
