The editor `root` namespace has collisions

[krispya]

There are multiple namespace collisions with root.

• The editor has a concept of root and at the same time, R3F also does. We keep track of both inside the editor currently and the names collide.
• Inside of ThreeEditorCanvas, FiberCanvas uses #root for its id causing invalid HTML since there is already a div with #root. I know this is being used with useId so seems like there needs to be a more robust solution than just removing it or change the name.
