Hot Reload update received but not applied

[BierDav]

Hot Reload stopped working after switching to v5. I tried finding the error and found out that:

The WebSocket connection works as expected but the engine doesn't apply the changes.

Prove:

Got the update.js with the new content. That means that the injected client side code doesn't apply the changes correctly.

are you sure it's not the same as #11773 ?

I think so yes, because I don't get a javascript error in the console.
