First a small typo in shadow’s document playground named “Fixed shadows“, semicolon in line 7 should be a comma to make the playground work.

document link: [Babylon.js docs](https://doc.babylonjs.com/features/featuresDeepDive/lights/shadows)

typo playground link: [https://playground.babylonjs.com/#PNQRY1#80](https://playground.babylonjs.com/#PNQRY1#80)

Then my problem playground link: [https://playground.babylonjs.com/#PNQRY1#246](https://playground.babylonjs.com/#PNQRY1#246)

I added a shadowDepthWrapper in settimeout with `standalone: true` in line 96, and getting error. Now I had to add shadowdepthwrapper to all my materials in my situation to escape the problem, is it expected?
