### Electron Version

18.0.3

### What operating system are you using?

Windows

### Operating System Version

Windows 10

### What arch are you using?

x64

### Last Known Working Electron version

18.0.0

### Expected Behavior

After entering and exiting fullscreen from an iframe and then focusing the parent page, <kbd>Escape</kbd> key events should be delivered to the parent page.

### Actual Behavior

<kbd>Escape</kbd> key events seem not to be delivered to the page after exiting fullscreen.

### Testcase Gist URL

https://gist.github.com/bc382eeeb368b70fbed1e177bcaacfde

### Additional Information

This only reproduces on Windows, not on macOS.

Also, this only reproduces when _clicking_ the "exit fullscreen" button in the YouTube embed. Pressing <kbd>Esc</kbd> to exit fullscreen allows the parent page to receive subsequent key events.

18.0.0 - not reproducible
18.0.1 - reproducible
18.0.2 - reproducible
18.0.3 - reproducible
