Note: This issue not happens every time. I don't konw why this problem happens. Seems no regular pattern.

This also occurs on OS X. Seems to have happened between March 31 - April 1st nightly. 

STR:
1) Browse the web
2) Try to go back - Sometimes the button is grayed out, sometimes clicking on the back button does nothing.
