[Bug]: Detached Dom Nodes memory leaks

[DanielBelmes]

Utilizing memlab and memory profiling I have detected a memory leak.

First image is a memory sanpshot of a refresh memory snapshot. The second snapshot is from a 10 min ran tab. Shown in the second is the specifics for the detached dom node.

@speigg @HexaField Pointing this in your direction as I'm unfamiliar with the Layers. There are other detached dom nodes here to check out as well.

Anything regarding XRUI (WebContainer3D, WebLayer) runs in a shadow DOM, I dont know how that affects what is displayed here, either way it worth investigating.

We also have a lot of video & audio nodes that are likely detatched, which is fine.
