Scene ready observable not firing with v5.35.0

@sebavan I’ve checked the diff between the 2 versions: Comparing 5.34.0...5.35.0 · BabylonJS/Babylon.js · GitHub

And it looks like the root observable class has been modified with: Observable: Do not include deleted observers in hasObservers result

I’ve just updated to v5.35.1 to reproduce the bug… but when I go to node_modules and manually comment this:

    /**
     * Gets a boolean indicating if the observable has at least one observer
     * @returns true is the Observable has at least one Observer registered
     */
    hasObservers() {
        return this._observers.length/* - this._numObserversMarkedAsDeleted*/ > 0;
    }

Everything is working fine :wink:

So… looks like there is a bug with your PR @Evgeni_Popov could you check please? :pray:

Edit: Related to Observable.hasObservers() is still true after removing all the observers - #4 by sharp
