Suspend/switch out of dom0 session in presentation mode

May someone help me to understand situation as follow?

QubesOS laptop with battery on normal charge range, active Presentation mode in dom0 switched out or suspend session without any reason and nothing mentioned on journalctl about it.

Maybe:

  1. Qubes 4.2 logged out when key combination is pressed (not the intended log-out one) · Issue #8710 · QubesOS/qubes-issues · GitHub
    But this one not mentioned as affect 4.3 and fixed by fedora.
