Minimal Map (QML) - Indicated min and max zoom levels are wrong

Description:

Indicated min and max zoom levels are wrong. It is not possible to zoom to the min level, while it is possible to zoom further from the max level.
Steps to reproduce

1. Open the Minimal Map (QML)
2. Zoom to the furthest possible point (will stop at 1, even if the min is indicated as 0)
3. Zoom to the closest possible point (will zoom to around 30, even if the max is indicated as 20)

Expected behavior:

The min and max zoom should be the same as the real min and max zoom possibility.
Observed behavior:

The indicated min and max zoom do not correspond to the real min and max.
