setInterval(()=>null,0) makes any animation much smoother

首先，在启用 Profile GPU rendering 的 Android 上复现链接的 NativeScript Playground，并比较空屏幕、setInterval(..., 0) 和 Choreographer.postFrameCallback 的情况。然后跟踪 Android runtime 中用于调度 setInterval 和 Choreographer 的入口点；完成的标准是解释或修正帧率差异，并在报告中提到的设备上验证该比较。

Environment

• CLI: 6.1.2
• Android Runtime: 6.0.2 / 6.1.2

Describe the bug
I'm working on custom animation (screen blinking at 60fps) on Android, and I was very surprised that using of stupid setInterval(() => {...}, 0) works much better that the native android's Choreographer.

With setInterval(() => {...}, 0) I've got stable 60 FPS even on android 5 devices, but with Choreographer (that should work much efficiency, code below) I got drops to 50 FPS on powerful OnePlus 6 on Android 9.0

android.view.Choreographer.getInstance().postFrameCallback(...);

But if I write down setInterval(() => null); near the Choreographer callback definition - I will achieve stable FPS and low GPU utilisation (LOL, right?).

To Reproduce
I have created app on playground where everybody can test it. Turn on 'Profile GPU rendering' - 'On screen as bars' in 'developer options' menu and launch this simple app with simple loader on 2 pages - one with absolutely empty component, another one with setInterval(() => {}, 0) in OnInit.

Sample project
Nativescript Playground

I've recorded animations to demonstrate this behaviour Imgur
