[Bug]: Copied/exported PNGs are blurry
### What happened?

I've noticed that when PNGs pasted into tldraw are exported/copied as PNG, the resultant image is blurry.

### How can we reproduce the bug?

In the project at https://www.tldraw.com/ro/nb7U7UwQt2AWvaoSoGecS?d=v108.-55.1912.1002.page I pasted a PNG image → right clicked → copy as → PNG and pasted it back in.

Please visit the link and zoom in to notice how the text is sharp on the left, and blurry on the right.
