'from' contains full jid in error stanza

[drizt]

I started jabberd on my personal PC. Version: jabberd-2.6.1-8.fc28.x86_64.

So when I send iq with no to attribute server reply has full jid from attribute but must be bare jid.

No to

<!-- Out 2018-07-19 10:27:17 -->
<iq type="get" id="no_to">
  <wrongelement xmlns="wrongns"/>
</iq>

<!-- In 2018-07-19 10:27:17 -->
<iq from="user1@lix/Psi" type="error" to="user1@lix/Psi" id="no_to">
  <error type="cancel" code="501">
    <feature-not-implemented xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
  </error>
  <wrongelement xmlns="wrongns"/>
</iq>

Bare jid to

<!-- Out 2018-07-19 10:27:36 -->
<iq type="get" id="bare" to="user1@lix">
  <wrongelement xmlns="wrongns"/>
</iq>

  </error>
