"It seems Firefox is the only browser to adhere to the specification in this regard."
I fail to see how being the only browser to honour the specification is anywhere near being a "fiasco" (which is defined as "a thing that is a complete failure"). There's most likely a reason for the way the specification is designed, and in this case Firefox should get credit for being the only browser doing it correctly.
