Zwave js UI - controller's icon state

[listhor (M)]

Starting from recent updates (3.10 and 3.11), zwave js UI doesn’t show current state of controller (most often was idle) and only “Unknown state”:

I use Zooz ZST39 (800 series) controller, with firmware 1.4 (with 1.2 was the same).
Only when I restored Zwave js UI to version less than 3.10, i.e. down to 3.9 - that icon was updated.
Is it only me or it is known bug?

? shows an unknown state for me as well, but it works fine.

Mine also works ok but I would like to have that icon nicely updated
