Thank you! Overall change seems to be valid and should not break
anything. Unfortunately, ATM I have some major technical difficulties
with testing and PC access overall. I try to find an opportunity to
test and verify it ASAP. Would you mind if I include note after ---
into commit message? (no additional actions needed from you).

Best regards,
Svyatoslav R.
