Steps to Reproduce:
1. Open writer and go to the menu bar -> Insert -> Image... and insert any image.
2. Make a right click at the inserted image and go to Properties... -> Image.
3. On "File name" enter the path to the image and click on OK.
The image is now linked but the the dialog from step 2 does not provide a possibility to rotate the image.
The possibility to rotate at least 90°/180°/270° (eventually even any value) should be provided in the dialog of step 2 without causing the image to lose its linked state.
