Make Background blurry behind a screenshot editor

after a screenshot is taken, the screenshot is put in front, smaller and able to be cropped, but the background of that screenshot editor stays sharp, so it can be pretty confusing when cropping the photo, and it would look aesthetically more pleasing.

Please make the background in the editor blurry.

Start by locating the screenshot editor shown after a screenshot is taken, then inspect how its background is rendered behind the crop view. Done means the editor background is visibly blurred while the screenshot remains in front and cropable.
