Thank you for a response.

I noticed about a strange message pass of a background.

The message which occurred on a card is passed to BG:
       card --> background group --> stack

This varies that a message occurred on a control:
       control --> background group --> card --> stack

Generally, not become a problem, but had better be careful.
