However, I cannot find a single implementation that reproduces the results shows at the bottom of that MDN page—not even close! Not Firefox; not Chrome; not Edge; not Adobe Illustrator...
So, I can't tell if the MDN documentation is correct, but nothing actually supports this (in spite of CanIUse reports), or if the MDN documentation is wrong.
