Environment

App: egui_demo_app (+ other egui-based apps)
OS: Windows 11
Git: 0bc59f5

Describe the bug

1. Open the 'input test' demo.
2. Click and hold Sense::drag
3. Move cursor off egui window
4. Alt-tab to a different window
5. Release mouse
6. Alt-tab back to egui window
7. Move cursor around
8. Mouse is erroneously considered pressed, even though it was released
9. Click mouse on egui window to fix state

Expected

Mouse should be detected as released once it is released. Other native windows apps seem to do this correctly, e.g. ms paint.
