Describe the bug When PNG exporting diagram with SVG file the output does not match what is seen in editor.

Originally tried to export as SVG and embed that in power point in Windows 11 but that demonstrated similar issue. Then switched to PNG and same thing.

Tried with latest draw.io desktop v26.0.4 in Ubuntu 24.04 as Snap image and it seems that Chrome displays the scaling of SVG nicely. But system viewer just blank on logos.

Tried also to set 300% scaling in PNG export so that more details would be present in PNG file but that does not seem to affect scaling issue.

To Reproduce Steps to reproduce the behavior:

1. Start draw.io (used one from Ubuntu's snap store)
2. Blank diagram
3. Create new library

• Add images: https://www.jenkins.io/images/logos/jenkins/jenkins.svg

4. From library add Jenkins logo two times -- one scaled one normal
5. Add thin box around them just to demonstrate scaling problem
6. Take screen shot how it looks
7. Export as png with default settings
8. Compare screen shot of draw.io and exported png -- observe the scale difference

Expected behavior They would look the same as in editor

Screenshots Screen shot with editor:
