createSprinkles with multiple collections that have the same property throws an error

Describe the bug

Passing multiple collections of properties to createSprinkles that share the same property (backgroundColor in this case) results in an error:

sprinkles.css.ts

import { defineProperties, createSprinkles } from "@vanilla-extract/sprinkles";

const responsiveProperties = defineProperties({
  conditions: {
    mobile: {},
    tablet: { "@media": "(min-width: 768px)" }
  },
  defaultCondition: "mobile",
  properties: {
    backgroundColor: ["red", "blue"]
  }
});

const stateProperties = defineProperties({
  conditions: {
    default: {},
    focus: { selector: "&:focus" }
  },
  defaultCondition: "default",
  properties: {
    backgroundColor: ["red", "blue"]
  }
});

export const sprinkles = createSprinkles(responsiveProperties, stateProperties);

App.css.ts

import { sprinkles } from "./sprinkles.css";

export const container = sprinkles({
  // backgroundColor: { default: "red", focus: "blue" } // works, but TypeScript complains
  backgroundColor: { mobile: "red", tablet: "blue" } // doesn't work, runtime error
});

ERROR in ./src/App.css.ts
Module build failed (from ./node_modules/@vanilla-extract/webpack-plugin/loader/dist/vanilla-extract-webpack-plugin-loader.cjs.js):
NonErrorEmittedError: (Emitted value instead of an instance of Error) SprinklesError: "backgroundColor" has no condition named "mobile". Possible values are "default", "focus"
