I'll be honest, I completely missed it as well, I had no idea the voting order was important. I see that many users wrote their preferences in a perfect numeric order, I guess they missed this part as well otherwise it would be quite a coincidence.
Bear in mind that not every browser correctly render that code.
I am currently browsing via my iPhone, and of course I cannot see it, and I am almost sure the same is from Safari on MacOS.
If this pice of information is so crucial, why not reporting it clearly?
Anyway, as I said, not much damage done, as there is a plenty of time to put everyone on the same page.
