Visible(true) event is not fired on plugin when session is reattached

[h1romas4]

Hello.

Basic information

zellij --version: zellij 0.37.2
stty size: 44 146
uname -av or ver(Windows): Linux thinkpad-p14s 5.19.0-45-generic #46~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jun 7 15:06:04 UTC 20 x86_64 x86_64 x86_64 GNU/Linux

Further information

The Visible(true) event to a plugin is fired when the session is first started, but the Visible(true) event is not fired when a Zellij session is detached-reattached.

Is it possible to change it so that the Visible(true) event is also fired on reattachment?

In the following example, the UI timer could not be started when detached-reattached a session.

fn update(&mut self, event: Event) -> bool {
    let mut render: bool = false;
    match event {
        Event::Visible(visible) => {
            // TODO:
            // If the Zellij session is detached, it is called with false,
            // but if it is reattached, this event is not fired.
            // Working on a way to restart the timer when it is reattached.
            if visible {
                set_timeout(0.0);
            }
            self.visible = visible;
        }
        Event::Timer(_t) => {
            // ..snip..
            render = true;
            if self.visible {
                set_timeout(INTERVAL_TIME);
            }
        }
        // ..snip..
    }
    render
}  

Reproduction

1. Build example plugin and lauch (fisrt session)

git clone https://github.com/h1romas4/zellij-datetime
cd zellij-datetime
cargo build
zellij -l plugin.kdl

2. Detach session (ctrl + o, d)

3. reattach session

$ zellij list-sessions
automatic-payment
$ zellij attach automatic-payment

Best regards.
