Image loading blocking p5 javascript projects

[MarcScott]

Summary

The draw-a-cat project works locally, but does not load correctly in the Raspberry Pi code editor preview when the sketch uses cat.png.

Project:
https://editor.raspberrypi.org/en/projects/draw-a-cat

Actual behaviour

In the editor preview:

• the page shows Waiting to load cat.png...
• the sketch stays stuck on Loading...
• the image is not rendered

Expected behaviour

The project should load cat.png and render the sketch in the editor preview, the same way it does locally.

Evidence

Attached screenshots show:

• editor preview stuck loading
• local version loading successfully and rendering the cat image

Reproduction

1. Open the draw-a-cat project in the editor
2. Run the preview
3. Observe that the image does not load and the sketch does not complete startup
