Hidden address book support - Larry skin, message compose

[pastafarian]

Hi

I've installed Roundcube 8.2 and have a couple of LDAP address books that are hidden using this config:

$rcmail_config['ldap_public'] = array (
  'ldap_internal' =>
  array (
  ....
  'hidden' => true,
  ...

When using the address book part of the application (https://my.roundcube.server/mail/?_task=addressbook), the address books do not show up in the list - as expected.

When composing an email however (https://my.roundcube.server/mail/?_task=mail&_action=compose), the two hidden address books display in the Contacts list.

Is anyone aware of any way that I can get the Larry skin to honour the hidden address book setting when composing a message?

Many thanks

Tony
