Steps to reproduce the bug

Hovering over this.a will result in the incorrect type being displayed as any. In theory, it should be number type.

Expected behavior

The type of this.a should indeed be number.

Actual behavior

The type of this.a will be any

The code hasn't changed in a while so probably it broke when upgrading some dependency like ts. Feel free to submit a PR!

In the meantime, you can use a setup() to spread the store properties:

setup() {
    return {
      ...storeToRefs(useStore())
    }
  },
