Wrong aspect ratio after scaling

[DSrhoj]

Aspect ratio of cropped image is not exactly the one set in cropProperties.

Steps to reproduce in demo app:

1. Select 9:16 aspect ratio from settings.
2. Zoom image in or out. Don't change crop area
3. Cropp
4. Result image does not have 9/16 = 0.5625 aspect ratio, but something slightly different

Same behaviour is in static and dynamic mode
I did not successfully reproduce this for 1:1 aspect ratio.
