Copying an emitter asset through the content browser will lead to cross communication when the two are used in the same system 

Steps to Reproduce
  1. Create a new emitter asset, choosing "Copy from existing emitter", select fountain as the emitter to copy
  2. In the content browser copy and paste the new emitter using ctrl+c and ctrl+v
  3. Open the newly copied emitter and change the particle color
  4. Create a Niagara system from the two emitters
  5. Disable the spawn rate module on the emitter that was copied from the original


Both emitters will stop spawning particles. Note: this does not happen if you create the second emitter in the same way the first one ("Copy from existing emitter")
