 @iamshashank this is a completely **invalid** Test Report, for two
 reasons:

 1. You have not used
 [https://core.trac.wordpress.org/ticket/63448?replyto=34#comment:31 my
 clear Test instructions]
 2. You have not tested the right patch.

 Please, guys, do a little effort and take some time to read thoroughly the
 full reports to understand what needs to be tested and how needs to be
 tested, do be like robots testing the first patch you see with the test
 information from the OP post only.
