I can confirm that this is broken in sage-9.2, but it works fine in
sage-9.3.  You should upgrade.

On Cocalc.com we keep a couple of older versions of Sage around:

~/cocalc/src/packages/next/components/account/config$ sage-.[tab]
sage-9.1  sage-9.2  sage-9.3  sage-9.4

Hi,

It works for me with SageMath 9.4. Maybe you should upgrade to that version 
(the last stable one).
