Focus when zooming and darkening background

[lineuxyz]

Hello,

I realized that when zooming the image, the background remains in focus, I think it would be cool when zooming the background to lose focus, getting darker and giving all the focus to the zoomed image.

This happens in some apps already.

This can be circumvented using a modal, however in my case the image will be zoomed directly into the user's feed, so the modal would not do.
