sample html file demonstrating the issue
in radial-gradient calc() works when adding lengths together, or percentages together:
radial-gradient(50px calc(50px + 1px), #f0f, #fff)
radial-gradient(50px calc(50% + 1%), #f0f, #fff)
combining length and percentage does not work:
radial-gradient(50px calc(50% + 1px), #f0f, #fff)

You should probably add another test with the simple radial-gradient(50px, 25%) case that doesn't' involve calc.
