Widgets added to IScreen before Hud.openScreen() finishes are lost

[Viorettas]

const screen = Hud.createScreen("My Input", true);
Hud.openScreen(screen);

Time.sleep(10);

const onSubmit = JavaWrapper.methodToJava((widget) => {});
const button = screen.addButton(20, 20, 100, 20, "Button", onSubmit);

As example code above, if time sleep is too low button sometimes appear sometimes don't. If u add widget before Hud.openScreen(), it doesnt appear. If u add widget after Hud.openScreen(), it doesn't appear if it doesnt waits until screen opens.
