Model overrides aren't evaluated when a previous override selected that model

There are three items model file: a.json, b.json, c.json
a.json:

{
  "overrides": [
    {"predicate":{"custom_model_data":1},"model":"item/b"}
  ]
}

b.json:

{
  "overrides": [
    {"predicate":{"custom_model_data":1},"model":"item/c"}
  ]
}

If tag CustomModelData of a item is 1, the display model is b.json, not c.json.
