In this case, fixity is a noun derived from the suffix “-fix” in words like prefix, postfix, infix. An operator's fixity is where it is positioned in expressions, in relation to its operands. Therefore fixity is a property of an operator, and the possessive “their” is correct.
Ah, okay. Apologies.
From the aside in 3.4.1
"their" should probably be "they're".
