In order to use a comma, you would need quotes around that value.
Here 2 different examples:
prefill_Vendor=circle,box
1) circle
2) box
prefill_Vendor=%22some%2C%20test%22,box
1) some, test
2) box

Prefilling a value that has a comma in it (encoded into the URL as %2C) the prefill doesn't work, even when the linked record itself has the commas.
