Custom Interface Extentions - Support for "table" type of custom

Is it my impression or the latest version of the SDK removed support for defining a table as a custom parameter? My extension reads data from another table as support for that has been recently added. In order to avoid hardcoding things, I was allowing users to select a table. This was supported  (see link below). However, the latest version of the SDK does not seem to support that. (^0.0.0-experimental-e7419444f-20251120). I’ve updated my code so the parameter is now just a string. It seems to be working. Could you please confirm this makes sense?

The signature of the type BlockPageElementCustomProperty I’m getting does not include that type anymore (see below) and I also get a run time error.

type BlockPageElementCustomProperty = {
    key: string;
    label: string;
} & ({
    type: 'boolean';
    defaultValue: boolean;
} | {
    type: 'string';
    defaultValue?: string;
} | {
    type: 'enum';
    possibleValues: Array<{
        value: string;
        label: string;
    }>;
    defaultValue?: string;
} | {
    type: 'field';
    table: Table;
    /** If not provided, all visible fields in the table will be shown in the dropdown. */
    possibleValues?: Array<Field>;
    defaultValue?: Field;
});
