Unexpected behavior residentKey = required with authenticatorAttachment=cross-platform

[Karen Tonoyan]

*Google Play services version: 23.17.15
*Android OS: 13
*Fido library: com.google.android.gms:play-services-fido:20.0.1
* Reproducible on any device

Trying to register Fido2 authenticator using Fido2ApiClient
Creating  AuthenticatorSelectionCriteria following way :

AuthenticatorSelectionCriteria.Builder authenticatorSelectionBuilder = new AuthenticatorSelectionCriteria.Builder();

Attachment attachment = Attachment.fromString("cross-platform");
authenticatorSelectionBuilder.setAttachment(attachment);

ResidentKeyRequirement residentKeyRequirement = ResidentKeyRequirement.fromString("preferred"); // or "required"
authenticatorSelectionBuilder.setResidentKeyRequirement(residentKeyRequirement);

Add authenticator selection criteria to PublicKeyCredentialCreationOptions.Builder and perform registration

Expected result: Roaming cross-platform security keys should be suggested for registration (see Expected_screen.png)
Actual Result: Platform authenticator with multidevice key gets registered (see Actual_Screen.png)
