I explored some source codes from some websites and I found this attribute in html tag: "data-scribe-reduced-action-queue". But I'm not found some document for describe it. Do you have references for me? Thanks. This is a example from Twitter:
<!DOCTYPE html>
<!--[if IE 8]><html class="lt-ie10 ie8" lang="pt data-scribe-reduced-action-queue="true""><![endif]-->
<!--[if IE 9]><html class="lt-ie10 ie9" lang="pt data-scribe-reduced-action-queue="true""><![endif]-->
<!--[if gt IE 9]><!--><html lang="pt" data-scribe-reduced-action-queue="true"><!--<![endif]-->
It is used to store custom data private to the page or application
