When "Allow louder than 100%" is checked, sound volume NotifyOSD shows the gauge only up to 100%

When "Allow louder than 100%" box is checked in sound system settings, change of the sound volume by the mouse wheel over the sound indicator leads to the gauge in the NotifyOSD showing the volume level only up to 100%. That is, the maximum value of the gauge in the NotifyOSD corresponds to 100% and further change of the volume louder than 100% does not modify the gauge state. At the same time, the gauge in the sound indicator drop-down menu shows the volume correctly, i.e. the maximum value of the gauge in the drop-down corresponds to the actual maximum volume "louder than 100%" and 100% is somewhere in the middle. The same behaviour is expected for the gauge in the NotifyOSD.
