additionalProperties is marked as a breaking change, despite not actually changing

Got some odd behaviour when using openapi-changes: it's marking a bunch of "breaking changes" that... aren't:

    {
      "breaking": true,
      "change": 1,
      "changeHash": "UUczar1_t-6gBj4TobhlsYmjEd0-LFbxZGC-3oP5rlA=",
      "changeText": "modified",
      "context": {
        "newColumn": 33,
        "newLine": 501,
        "originalColumn": 33,
        "originalLine": 949
      },
      "new": "false",
      "original": "false",
      "property": "$ref"
    },

There are 20 of these in total, each related to the same element: "additionalProperties": false
