I see that nothing handles cyclic deps. I took a stab at it because it's breaking for me, but I notice that the cyclic dep resolver isn't working properly. When I install es-abstract, I get in the dream lock (trimmed example):

{
    "string.prototype.trimend": {
      "1.0.5": [
        [ "es-abstract", "1.20.1" ]
      ]
    },
    "string.prototype.trimstart": {
      "1.0.5": [
        [ "es-abstract", "1.20.1" ]
      ]
    },
}

Obviously, all cyclic dependencies should be grouped together and a parent dep should be picked (probably the one with the shortest name)

So it should be:

{
  "es-abstract": {
    "1.20.1": {
      ["string.prototype.trimend", "1.0.5"],
      ["string.prototype.trimstart", "1.0.5"]
    }
  }
}
