Unexpected Behavior in 'Tips' Documentation -- re: window.hide() & always-on-top

Description

My overarching goal is an app that is a "pure" menubar, targeting specifically macOS users, with the purpose being to show at-a-glance data in the menubar along with additional detail & quick "controls" when the app is open. I want it to function similar to most macOS menubar apps (ie 1Password) -- when focus is lost, the window should hide completely.

The 'Tips' section of the documentation specifies the following:

Use mb.on('focus-lost') if you would like to perform some operation when using the option browserWindow.alwaysOnTop: true

Steps to Reproduce the Problem

1. Based on the 'tips' part of the README, I used the following code to cause the window to hide when focus is lost:

mb.on('focus-lost', () => { mb.window.hide(); });

1. With the menubar app open, click anywhere away from the menubar app (causing it to lose focus).
2. After closing the app via clicking outside of it [ie loss of focus], now attempt to re-open the menubar app via clicking it in the macOS menubar.
3. Note that it does not open upon clicking it; a second click is required to get it to open.

Expected Behaviour

After closing the app via clicking outside of it [ie loss of focus], any future click on the app in the macOS menubar should re-activate & display the app/window.

Actual Behaviour

After closing the app via clicking outside of it [ie loss of focus], any future click on the app in the macOS menubar will intermittently (seems to toggle/alternate) have no effect / be a no-op click (window does not display). Clicking it a second time opens the window.

Specifications

• Menubar version: 9.0.2
• Platform: macOS Big Sur (11.2.1)
• Electron version: 9.4.3

Other information

It appears that using the following code, instead of the code above, actually causes the behavior to be as expected -- ie it resolves the issue -- so maybe this "issue" can just be 'fixed' via simply updating the documentation, I'm not sure.

mb.on('focus-lost', () => { mb.hideWindow(); });

If nothing else, I'd like to understand why this works & the approach that I tried initially does not; and if there is a way to make my initial approach work I'd love to hear & learn/understand it (ie do I need to call/init the window again somehow, or listen for menubar click manually & call show(), or similar). :)

Thank you very much; this is a fantastic project and I very much appreciate all the work that has gone into it! It's really quite nice -- thank you! :)
