Spacer widget missing from widget selector in new installs

I usually use two spacer widgets to center the “Icons-Only Task Manager” in my panel. A few updates ago, the spacer widget disappeared from the widget selector. In my old installations it still appears, but it’s missing in new installs.

Is this a bug, or was it forgotten in a package/repo? Or should I just wait until the “Icons-Only Task Manager” gets a native center option?

This is intended. The spacers are now found in the panel configuration, as it makes more sense being here.

in my panel configuration is not appering that. I do something wrong?
