"Update Metrics" command does not update width metric if 0

Hello, I noticed something:

I emptied a softhyphen that previously had contours and set the left and right metrics key to =0, as well as the the width key. If I click Glyph > Update Metrics, the side bearings update, but not the width. So my empty softhyphen still had a width of 300 (for example). I had to click on the circle arrow in the glyph info panel to update the width.

Set width=0, not the sidebearings.

You can’t set metrics keys of both side bearings and the width. In this case only need the width.
