Composing message when focus is on side-panel leaves it open in `--autohide` mode

[zee-bit]

Composing a message using x or c when the focus is on either of the side-panels, leaves it open when --autohide is specified as a command-line arg. A similar case happens when opening a draft with either of the side-panels open, which is discussed briefly in #zulip-terminal>Bug: Drafts focus.

This can lead to some easily reproducible cases where both the side-panels are open, which seems a bit strange for --autohide. We would like to have a general approach that can handle these corner-cases(and probably other similar cases) gracefully.

I can't reproduce this on main, and it looks like this was fixed in c96931a in #1100 (August 2021), so closing this now.
