Reconnect gets stuck in an infinite loop

[jimbobbennett]

I'm implementing reconnect logic in my Azure IoT library, and I've hit what looks like an in infinite loop in the reconnect logic.

When I call reconnect, the function call never ends. A quick read of the code shows this:

while self._subscribed_topics:
    feed = self._subscribed_topics.pop()
    self.subscribe(feed)

LInk:

Adafruit_CircuitPython_MiniMQTT/adafruit_minimqtt.py

Line 617 in bd24155

while self._subscribed_topics:

The subscribe method puts the topic onto the _subscribed_topics list, so this list is never empty and the while loop never ends.
