Command 19 (IS_CONNECTED_TO_ROUTER) return invalid JSON (Firmware: 1.1.0)

[tinodo]

When issuing command 19 to my light bulb, running Firmware 1.1.0, over TCP, the device returns an invalid JSON response.

Request: {"cmd":19}\r\n
Response: {"res":0,"cmd":19",ip":"192.168.1.169"}

As you can see, there is a double quote missing before the ip property, and one too much after the command number (19). It appears the comma and the double quote are swapped. It should be:
{"res":0,"cmd":19,"ip":"192.168.1.169"}

Has this been fix in later firmware? (I am unable to update the firmware using the provided Android app).
