Error with Crop

[Sleepw1]

Describe the bug

There is something wrong with either the "rotate and perspective" or the "crop" module. If you rotate an image, for example 10 degrees, and later use crop to crop the image, the frame in the crop does not match the actual result.

Steps to reproduce

Use "Rotate an perspective" to rotate a picture, later crop the image with "crop" module.

Expected behavior

Crop to correct size.

I have tested this on current master and I can confirm the issue.

One essential information is missing in above issue report:
This only happens if crop is set to the aspect ratio "original image"

@jenshannoschwalm could this be related to #16976 ?

Image and xmp file. peras.net/pp/PAS_1798.CR3, peras.net/pp/PAS_1798.CR3.xmp

[Sleepw1]

When the image is in portrait format: The error occurs on the right side of the image.
When the image is in landscape format: The error occurs at the bottom of the image

@Sleepw1 your issue will be solved once PR #17052 is merged into master or 4.8.1

Thank you for reporting!
