[keycloak-user] How to handle multivalued custom attributes in account client?

Hello, I’m facing a scenario where I have defined a custom attribute as multivalued. It works all fine using the REST admin API, and while in the Keycloak admin console is displayed as a ‘##’ separated string, it’s also functional in terms of displaying/editing the values. However, when it comes to adding the attribute to the account client, it apparently only shows the first element of the attribute, and I get the following log trace: Am I overlooking some configuration to enable the handling of multivalued custom attributes?
