@lmangani your welcome, this needs to be tested further but this would help me out alot. Thanks
I have another issue when building, because the package.json uses latest version and the docker build
does npm install and build fails because of latest version changes. If you want me to fix and send another pull request please let me know.

unfortunately the patch breaks share link and another components. We changed it a bit and you can provide the path in the index.html right now (static) We are working on a new solution.
