Mouse up events are ignored on native if cursor moves to another window in between.

[jakobhellermann]

When you mousedown on a window, drag outside of it and release, the press state in egui is cleared correctly (at least on native, in browsers this doesn't seem to work #101).

But when you mousedown on window A, drag over to window B, release, then the state is kept until you click in window A again.

Here's an example, printing

println!("Window 1 (or 2) {:?}", ui.input(|input| input.pointer.press_origin()));

in two_windows.rs:
