    Description

      Since Qt decided to remove its Location module and since our app needs map display capabilities, we are trying to display a map inside a QML WebView. The map is described inside an HTML file. The HTML is loaded as a string into a QML WebView using WebView::loadHTML. The HTML renders great under Windows by just double-clicking onto it. But WebView displays an empty black window...

      Repro case:

      • Use attached HTML file and double click it: it opens fine.
      • Instantiate a QML WebView and use loadHTML to load attached file as a string: WebView displays an empty black window.

      Android log displays these errors:
