Phantoms 2.11 JS doesn’t handle various Webworkers at the same time.

I have an application using Phantoms JS 2.11 that uses a pool of webworkers. I couldn’t make it work. I changed my code, and set only one webworker at a time (I implemented a queue), and it worked perfectly.

I couldn’t find anything on the web about that problem, so I am posting that here.
