LO 5.1.0 Save Button icon NOT fading after save

Just updated to LO 5.1.0 and noticed the [Save] icon does NOT fade after performing a save nor when a document is already saved.

WHY?

Need [Save] icon fade function back.

This topic is discussed with Why did you change the save button ? - 2016 Edition. The save button has been changed and no longer fades after saving. Instead there is a star which appears on the icon when the file has had changes and will need to be saved. There are users on both sides of the camp… Peter
