iced_native::input::mouse::Event::CursorLeft not emitted when the cursor leaves the window

[Plecra]

• Platform: Windows
• iced_native version: 0.2.0

When the cursor leaves the window, buttons will continue to display their drop shadow, instead of reacting to the cursor leaving.

You are right. Thanks for reporting!

I have implemented a fix in #289.
