QtCreator expect icon declaration being exactly android:icon="@drawable/icon" and removes any other values (e.g. android:icon="@mipmap/ic_launcher")

Nowadays whole Qt Creator's icon set generator feature become useless, as it generates only 'legacy' icon set for devices with Android API level 24 and older. Actually you use an icon set generated by external tool (with newer adaptive and monochrome icons) and add definition to AndroidManifest.xml, common value here is android:icon="@mipmap/ic_launcher", its annoying that "Android Manifest Editor" removes it each time you double clicked at  AndroidManifest.xml in project tree.
