MINI-ZBDIM does not work properly when setup with single button (momentary)

What happened?

When the device is setup as momentary and connected to a single button (L - S1) the button can turn ON the load (short press), dimmer it up and down (long press) but it will never goes to OFF with again short press.
The only way to turn it off is to long press and hold it until brightness is 1%.
from the Z2M GUI (or Home Assistant) I can toggle ON and OFF without any problem.

What did you expect to happen?

toggle ON/OFF the load with short press not just ON when OFF and never OFF when ON

How to reproduce it (minimal and precise)

as said, short press from OFF turn the device ON but then there's no way to turn if OFF with short press

Zigbee2MQTT version

Adapter

Sonoff Dongle MAX Pro

Setup

Zigbee2MQTT on his own LXC container, ProxMox server; Home Assistant is on a VM on the same ProxMox server but it's irrelevant for the issue I have

Notes

No response

Start by reproducing the MINI-ZBDIM issue with the momentary single-button setup described, using short presses from OFF and ON while collecting a debug log. Trace the device handling for model MINI-ZBDIM and its on/off and level-control behavior; done means a short press toggles the load both on and off.
