[css-transitions-1] transition-property conflicts about whether multipe alls are allowed

[fantasai]

<single-transition-property> = all | <custom-ident>;

A value of none means that no property will transition. Otherwise, a list of properties to be transitioned, or the keyword all which indicates that all properties are to be transitioned, is given.

The syntax says 'transition-property: all all' is valid, but the prose says it's not. Pick one option and stick with it? :)
