DNS Leak while using Waterfox on Android with VPN

[garteful]

What happened?

Hello, I'm writing to report a possible issue with Waterfox on Android. I'm using NordVPN service and I noticed that my DNS addresses are exposed when I visit websites like ipleak.net, dnsleaktest.com, etc.. This does not happen when I use other Android browsers (Vivaldi, Fennec) with VPN. I'm not sure if this is a bug or a configuration problem on my end, so I apologize if this is not the right place to ask. Thank you for your attention and assistance.

Reproducible?

• [X] I have checked that this issue cannot be reproduced on Mozilla Firefox.
