Plugin does not send Home Assistant auto-discovery messages

My system is as follows:

Decent De1Pro 1.45
Teclast P85Pro (comes with Android 12)
mosquitto broker on current home assistant version

I installed the plugin on the decent and configured it as described in the docs. I also disabled all battery saving functions I could find.

Issue: The HA auto-discovery messages were not published to the broker. I checked that by subscribing to topic "homeassistant/#" on the broker.

I manipulated the code (as others in the diaspora did), that the messages would be send regardless of connection state in the method on_con_event:

proc on_conn_event {topic data retain} {
        variable current_status
        # Republish our status each time we reconnect
        msg "received conn event: $data"
        if {[dict get $data state] eq "connected"} {
            msg "connected"
            # Publishing directly inside a CONNACK event callback unfortunately
            # doesn't work, since the mqtt library hasn't stored the fd yet,
            # and it just drops the publish message.  Therefore use an after
            # call to schedule this publish.
            after 1 ::plugins::mqtt::post_connect_publish
            set current_status "Connected"
        } else {
            # The mqtt package unfortunately does not deliver connection events
            # to us with the TCP connection is refused.  We only mostly only
            # get connection events after the connection is established and the
            # server sends a CONNACK packet.  Therefore on TCP connect errors
            # our current_status will unfortunately just remain as
            # "Connecting..." in most cases.
            msg "connection status: $data"

            after 1 ::plugins::mqtt::post_connect_publish
            msg "not connected but running post_connect_publish anyway"
            switch -- [dict get $data reason] {
              0 {set reason_str "Connection Accepted"}
              1 {set reason_str "Unaccepted MQTT Protocol Version"}
              2 {set reason_str "Client ID Rejected"}
              3 {set reason_str "Server Unavailable"}
              4 {set reason_str "Bad Username or Password"}
              5 {set reason_str "Client Not Authorized"}
              default {set reason_str "MQTT code $data(reason)"}
            }
            set current_status "[dict get $data state]: $reason_str"
            msg "connection status: $current_status"
        }
    }

But that did not work. I also didn't see the loggings from this function in the log. It seems, that this method is never called. Nonetheless the plugin started to publish status messages.

I then added the line after 1 ::plugins::mqtt::post_connect_publish at the end of start_client, which worked. After that I removed the line again.
