  Question/bug

• What is the current behavior?
  I'm having an issue with the application not working with buffer set to true. (works if I turn off buffer). What happens is that the visible app-root is completely unusable while the hidden one with display: none works correctly. The pre-rendered version should be removed or hidden from the DOM once the client finishes bootstrapping, but in this case it doesn't happen.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem by creating a github repo.
  I only added PrebootModule.withConfig({ appRoot: 'app-root' }), to app.module and
  applied a fix for the flickering issue mentioned Big FOUC as server side styles removed before the switch to client side #75 (comment)

• What is the expected behavior?
  It should remove the pre-rendered selector from the DOM after the client is finished bootstrapping.

• What is the motivation / use case for changing the behavior?
  I need help getting this fixed
