Scene failing by timeout doesn't notify the renderer

[kuruk-mm]

When a scene fails for timeout:

kernel/packages/shared/world/SceneWorker.ts

Lines 221 to 228 in 29238aa

	const WORKER_TIMEOUT = 90_000 // three minutes
	setTimeout(() => {
	if (!this.sceneStarted) {
	this.ready |= SceneWorkerReadyState.LOADING_FAILED
	workerStatusObservable.notifyObservers(signalSceneFail(this.loadableScene))
	}
	}, WORKER_TIMEOUT)

The renderer doesn't get notified about it, and the loading gets stuck forever.

Example coordinates: "-20,26", "-19,26", "-20,27", "-19,27", "-29,26".

Note: This issue doesn't try to fix the issue in the scene itself. It's a fix for the explorer.

Partial fix from: decentraland/explorer-desktop#386
