[Request] Add default to remove modal

I have been using this package for a long time in a lot of projects and recently ive noticed a lot of issues regarding modals mounting and un-mounting especially with forms.

Most UI packages have modals built with open / closing animations and id like to use that closing animation, so if I just call modal.remove() the animation is not displayed. Ive tried to do an async call like this:

const handleClose = async () => {
  return modal.hide().then(() => modal.remove())
}

however in that scenario I have noticed that the modals are not actually being removed from the component tree and if I were to open that modal again, the form values still display the values of the previous modal because it did not get removed and re-rendered.

Start from the modal.hide() and modal.remove() APIs and reproduce the reported form-state behavior with a closing animation. Trace how hiding and removing affect the component tree, then define the default removal behavior so the animation can complete while the modal is actually unmounted and reopened forms do not retain prior values.
