QtWebEngine crashes on device when trying to load site while offline

When trying to load site while the device is offline, the application crashes. The same crash also happens when trying to load certain sites (such as https://www.toradex.com). This happens at least on Apalis iMX6D running Boot2Qt 2.0.2. On desktop (Tested on OpenSUSE Tumbleweed) it does not crash. Also works on 5.7.0 so this is a regression.

Steps to reproduce:
Run WebEngine QtQuick Minimal Example while the device is offline -> Crash
OR
1. Load WebEngine QtQuick Minimal Example
2. Change url on main.qml to https://www.toradex.com
3. Run the example -> Crash
