There is no way to realize when to render scene in requestRenderMode

[a-milenin]

What happened?

Calling scene.requestRender() after adding entity and on collectionChanged does not have any effect. Only way to make it work is a delay before requestRender but I don't think it's how it should works.

Reproduction steps

1. Open link
2. Click toggle couple times
3. It supposed to appears/disappears after each click but it's not
