Description

From the google community:

there is a major issue with the metadata, which make it unusable for me:
Editing (rotate, flip, ..) and saving the image deletes all the metadata from the image.

I've confirmed that exif metadata and image attributes are lost.

Research direction

Start by locating the save-on-modify path for rotate and flip operations, then reproduce the issue with an image containing EXIF metadata and image attributes. Trace where the edited image is written and verify that saving preserves both metadata categories; done means the metadata remains after modification and reload.
