Excalidraw plugin incompatibility

[LorinczAdrien]

When using Excalidraw plugin, pasting an image (whether the "Import Attachments+" pop-up appears or not) leads to the image showing up as expected, but then cannot be saved successfully by Excalidraw:

Steps to reproduce:

1. Create a new vault
2. Add Excalidraw & Import Attachments+ plugins (enable them as well)
3. Create a new Excalidraw drawing
4. Paste an image
5. Try to save
