Api and Qt related issues with Bing and Google services

[rduivenvoorde]

A message on the QGIS-user list:
https://lists.osgeo.org/pipermail/qgis-user/2020-January/044609.html
made me do some tests with the plugin.

While OSM still loads/looks good, apparently the different commercial api services like Google and Bing have troubles loading in recent (3.x) QGIS versions.

Google shows the following QGIS warnings:

2020-01-02T09:16:34 WARNING Python error : An error has occurred while executing Python code: See message log (Python Error) for more details.
2020-01-02T09:16:34 WARNING OpenLayers Plugin : Printing and rotating of Javascript API based layers is currently not supported!

AND a javascript popup in the map:

This page can't load Google Maps correctly.

Bing has other issues:

2020-01-02T09:20:37 WARNING OpenLayers Plugin : Printing and rotating of Javascript API based layers is currently not supported!
2020-01-02T09:20:37 CRITICAL Qt : QNetworkReplyImplPrivate::error: Internal problem, this method must only be called once.

Not sure if this is an api issue, or just because the webkit/browser components of Qt are getting more strict or technically behind...
