Description
In the project properties one can set desired units for elispoidal distance and area measurements, among other values it is possible to select "Map units (…)". When the "Map units(…)" value is selected, some of the "Derived" identify values, namely ellipsoidal area and perimeter does not have units text after the value.
This is because in the project properties "Map units(…)" is represented as an unknown unit (
Qgis::DistanceUnit::UnknownandQgis::AreaUnit::Unknown). As a result,displayDistanceUnits()anddisplayAreaUnits()method of the identify action return empty string. This also affects conversion of area and perimeter measurements in identify tool.Fixes #26995.
