[Regression] Qml Positioning with nmea source file does not work

The QML type Map does not update when position source is nmea file source.

Steps how to reproduce:

Please run the attached example project.

Expected outcome:

The map is updated with nmea position source file.

Actual outcome:

The map is not updated with positions from the nmea source file.

This works with Qt version 5.13.2 and 5.12.8 so it seems like a regression.
