Tree disappeared #42
Description
The sidebar tree was showing up fine; I was trying to colorize the tree using set -g @sidebar-tree-command 'tree -C' and now the trees do not show up. The pane is blank. I can open up the help menu using h, but no tree. I do not understand how to reproduce this either. System: Debian 5.10.92-1, tmux 3.1c with darcula theme.
