We are using recommendedResolutionSelector._previousResolution to see if the resolution had changed before highlighting the resolution selector. This updates when intents change but not when qualities change.
I tried updating when the qualities change but this was updating before this line
if(recommendedResolutionSelector._previousResolution !== Cura.MachineManager.activeQualityType)
which caused this always to resolve as true
The solution was to update _previousResolution after we select an item in the drop down.
