2.9 edit mode transform to sphere?

is it possible to make a nice circle using the mesh transform to sphere in 2.9 ?

when i select verts it does not find the middle of the verts
and transform does not work nicely

Works in 2.93.8 with default preferences:

Also I noticed small bug - hotkey is bound to 3d View category so it can be used in both edit and object mode (even though it can’t actually do anything in object mode).

you go directly to the operator
which seems t o work better and at least find the middle avg verts

i was using the mesh transform to sphere
and that one seems to still have bug may be
cannot find the middle verts avg!
