When zoomed in, things like moving planner points is not possible,
but if the user attempts that, replan() -> plotDive() is called
and the zoomLevel should be reset to the default value (we don't
really want that), but instead it's lost for some reason
(as the user reports: "Somes times, it changes to 100% which is ok").
If moving points becomes possible eventually while zoomed in,
we need to figure a way to replot without resetting the zoom level
in plotDive().
