The problem is basically the same bug as #35044. Base.operator_associativity defaults to returning :left, and misses the case for :?.

julia> Base.operator_associativity(:?)
:left

Expected behavior:

Return :right as that's the precedence for the ternary operator. As documented in Operator Precedence and Associativity
