I doubt it's monotonic, though it's probably not a practical problem. That is, it would probably be totally impractical to try to use the nonmonotonicity for anything strategic, and it wouldn't even lead to Yee diagram ugliness.
Nonmonotonicity could be considered an error even with honest voters. The argument would go something like: "Okay, if we raise X, then X goes from winner to loser. That means that the method is either wrong about who should have won in the ballot set before we raised X (it shouldn't have been X), or after we raised X (it should have been X). We have no way of knowing which is the 'right' result, and so other results could also be suspect".
