[Bug] Failed to hide widget after playing

[sheepbox8646]

Describe the bug Before playing the animation (called app.play()), you can freely change the visible of a widget, but after playing, you can only show and cannot hide, and the widget.display.value is always keeps true.

To Reproduce Steps to reproduce the behavior:

1. Go to directory ./examples/scene1.ts
2. To reproduce, please type following codes:

import {Circle, createScene, move, Rect, Widget} from 'newcar'
// import TextEditor from "@newcar/mod-text-editor";
import * as nc from "newcar";

await nc.useFont('./default.ttf')

export default createScene(
  new Circle(100, {
    x: 100,
    y: 100
  })
    .setup(function *(widget) {
      yield 1
      widget.hide()
      console.log(widget.display.value)
    })
)

According to the image and output, you can easily discover that only a nick of time you can see the false was put into outputs, either was true.
