[FEAT] Revert or add an option to disable "Focus goes back to your last app"

[Stolka]

Is your feature request related to a problem? Please describe.

Focus goes back to your last app: Closing QuickView returns the keyboard to the program you came from (Explorer, a browser, another viewer, and so on).

This behavior is unusual, you can try by opening an image with any image viewers such as Windows' built-in Photo, ImageGlass, or BandiView, none of them returns to the program where the image came from.

For example if we open an image from File Explorer.
Current behavior: File Explorer > QuickView > Chrome > close QuickView > File Explorer
Common behavior: File Explorer > QuickView > Chrome > close QuickView > Chrome

Describe the solution you'd like
QuickView shouldn't modify the focus or at least add an option to disable it.
