How to share WORKERFS with browser module by PROXYFS ? 

I want to use `FS.createLazyFile` which is only supported by worker.  
And I also build a SDL project which can not by in a worker. 
So that I want to use proxyfs to mount workerfs. 

But the FS in worker can not pass through to the window because of the `‎DedicatedWorkerGlobalScope`.
I wonder how to shared the FS between the worker and the window.
