Do you see anything in the log? Is it random, or is it always after going back to the page that the reader mode icon isn't shown?

I kept investigating this as I do not get anything in logs but it is still intermittent on mostly all devices( Nexus-es, S5) or you get no reader icon at all on Note 2. 

1. Open link - no icon
2. Refresh or Open new tab and load page again - icon present
3. Repeating 2 several times will display the page without icon in url from time to time.
