In our experience, it's possible for the colorstop.stop to be less than zero, but only in Firefox. When this happens, you get the dreaded "IndexSizeError: Index or size is negative or greater than the allowed amount".
This often manifests as -0 or a very small negative number, so it seems pretty safe to just force this to zero.
Replicating this error is not easy and I don't currently have a live site to demonstrate it with, so I'll try to find out more. We're currently patching dist/html2canvas.js.
