References:

tmux 2.6+ requires that the window be viewed with the client before
select-layout adjustments can take effect.
To handle this, this function creates temporary hook for this session to
iterate through all windows and select the layout.
In order for layout changes to take effect, a client must at the very
least be attached to the window (not just the session).
hook_name is provided to allow this to set to multiple scenarios, such
as 'client-attached' (which the user attaches the session). You may
also want 'after-switch-client' for cases where the user loads tmuxp
sessions inside tmux since tmuxp offers to switch for them.
Also, the hooks are set immediately unbind after they're invoked via -u.
