Describe the bug
When I export a draw.io diagram that has images as a png or webp, result image looks blurry. Drawio shapes and text look fine though.
The latest version that still produced non-blurry exports was 27.0.9.

To Reproduce
Steps to reproduce the behavior:

1. Insert a picture into drawio diagram
2. Click on Export As -> Png
3. Set zoom to 100%, leave other options unchecked
4. Export image and compare to the original image.

Expected behavior
Exported image should be the same quality as a source

Screenshots

For me the png is always blurry and unusable. I wonder why, png as image format should be lossless right?
Great for text, shapes etc.
