Volume widget no on screen display

I have noticed using the default widgets for brightness and volume that when pressing the icons for vol up/down the on screen volume display doesn't show, however if I slide the slider it does show.
The brightness widget displays the on screen display when both sliding and pressing the up/down buttons at the end of the widget.

It would be nice to have the volume widget behave as the oem widgets do (same as brightness currently does and display the on screen volume display)

It improves the user experience so much
