`WindowEvent::Focused(false)` emitted on startup on macOS

[emilk]

Description

In winit v0.30.12, one of the first emitted events is WindowEvent::Focused(false), despite the window getting focus on start. Calling widow.has_focus() yields the correct true.

Switching away from the winit app (with cmd-tab) yields another WindowEvent::Focused(false).
Only when switching back to the winit app do we get the first WindowEvent::Focused(true).

Interestingly, this is NOT an issue on latest master.
With winit 0.31 having no due-date, I think this would be nice to fix in 0.30.x.

Repro: cargo r --example window

I found this old pair of issue/PR:

• Macos fires WindowEvent::Focused(false) on WinitWindow creation #2695
• On macOS, fix initial focused state #2696

Seems like we have a regression.

Workaround

Ignore the value of WindowEvent::Focused and only trust window.has_focus()
