Errors trying to paste/open an SVG file

[1j01]

Trying to paste an SVG image I copied to the clipboard (the uBlock Origin logo), I got an error:

InvalidStateError: CanvasRenderingContext2D.drawImage: Passed-in canvas is empty

Saving it and trying to open it instead, I got a different error:

IndexSizeError: Index or size is negative or greater than the allowed amount
