Bug description

Backgrounding a process with ctrl-z (e.g. a running vim) causes the background processes to be killed.

Expected behavior

Nothing (where "nothing" means whatever bash would normally do with a ctrl-z'd process).

Steps to reproduce

1. Open cmux
2. Run vim (or anything else that stays running in the foreground)
3. Send ctrl-z
4. See something like the following output:

$ vim bashrc

[1]+  Stopped                 /opt/homebrew/bin/nvim bashrc
bash: warning: deleting stopped job 1 with process group 47532
[3]   Done                    { local branch dirty_opt=""; branch=$(git branch --show-current 2> /dev/null); if [[ -n "$branch" ]]; then
    local first; first=$(git status --porcelain -uno 2> /dev/null | head -1); [[ -n "$first" ]] && dirty_opt="--status=dirty"; _cmux_send "report_git_branch $branch $dirty_opt --tab=$CMUX_TAB_ID --panel=$CMUX_PANEL_ID";
else
    _cmux_send "clear_git_branch --tab=$CMUX_TAB_ID --panel=$CMUX_PANEL_ID";
fi; } > /dev/null 2>&1
