TLS MQTT connection successful even with incorrect Common Name

[smilexs4]

I have an EMQX docker container running at 192.168.137.213, with TLS enabled. The self signed broker certificate was auto generated, the Common Name is "Server", however my ESP32 with fingerprint auto learning is able to connect successfully.

Shouldn't the connection fail since the broker's IP address specified in the MQTT config is different from the Common Name?
