getDeclarationModifierFlagsFromSymbol(symbol)was returningModifierFlags.Readonlybased on the.valueDeclaration..valueDeclarationis only set on union/intersection properties when it's "uniform"(ish). In this example, one source property symbol had a.valueDeclarationand the other one hadn't (the one from the mapped type hadn't it)
