ProjectionManager: the `mode === null` guard can never pass — OrthoPerspectiveCamera.mode throws when uninitialized, so projection.set() before world assignment throws instead of no-op

[stokuewe]

Versions

@thatopen/components 3.4.8 (verified against the published dist/index.mjs; source: packages/core/src/core/OrthoPerspectiveCamera/src/projections.ts + index.ts).

What happens

setOrthoCamera() opens with a guard written as a silent early return:

if (this._component.mode === null) return;

But mode is a getter that throws when _mode is unset:

get mode() {
  if (!this._mode) {
    throw new Error("Mode not found, camera not initialized");
  }
  return this._mode;
}

_mode is only populated in the camera's worlds.onItemSet handler, i.e. on world.camera = camera. So calling projection.set("Orthographic") (or toggle()) on a camera that has not been assigned to a world yet throws Error: Mode not found, camera not initialized out of a line whose intent is clearly a no-op. As written, the === null comparison is unreachable dead code.

Repro

const camera = new OBC.OrthoPerspectiveCamera(components);
await camera.projection.set("Orthographic"); // throws — expected: no-op or clear error

Suggested fix

Check the backing field (this._component._mode via an internal accessor / a hasMode getter) so the early return works as intended.
