fix(useMagicKeys): reset refs on target blur

[lavolpecheprogramma]

Description

On macos when some keys are pressed in combo(cmd+p for example) open a dialog and the keyup is not triggered and the refs keep a wrong state.
I add a blur event listener so when the target lost the focus, the key refs are resetted to false.

fixes #1350
