Possible spelling mistake on docs.emmet.io/cheat-sheet/

[IAlwaysBeCoding]

So either perhaps my sublime 3 emmet plugin doesn't implement the correct way, or there is a spelling mistake on http://docs.emmet.io/cheat-sheet/.

Basically, Alias of button[disabled.] should be Alias of button[disabled] same goes for
Alias of select[disabled.]
Alias of fieldset[disabled.]
