Unexpected collision log

[TrevorRice]

As discussed in #1308, the following two files:

// colors-1.json
{
  "colors": {
    "$type": "color",
    "black": { "$value": "#000000" }
  }
}

// colors-2.json
{
  "colors": {
    "$type": "color",
    "white": { "$value": "#ffffff" }
  }
}

Result in the following console log despite the tokens being generated correctly:

Token collisions detected (1):

Collision detected at: colors! Original value: color, New value: color

This can be demonstrated in this minimally reproducible example.

Removing "$type": "color" from one or both of the files resolves the collision logging issue.
