 * The document.write issue only appears, if you have the defer for PSI option enabled
   and render blocking scripts. There is no way around it.
 * On FVM 3 I have decided to remove this option.
 * Instead, you can now manually choose which third party scripts should be delayed
   until user interaction, or up to 5 seconds (whichever comes first).
    This method
   delays the scripts (but check if your script supports this and doesn’t trigger
   errors), which is important to reduce the amount of data downloaded on the initial
   request.
