### Actual behavior

As a developer using the 5.0.0-next release
When using the measure component (either 2d area or 2d line)
And when changing the dropdown unit
Then the distance, area and perimeter units are not updated within the component.

_note: the label is correctly added to the drawn graphic on the map, this is specifically referring to the units displayed within the measurement component_

### Expected behavior

As with previous releases and as expected, when selecting the dropdown to change unit within a measurement component, then the values should be reflected within the component itself.

E.g. when changing to cm, then it should read cm in distance and perimeter. Also cm^2 in Area.
