4. Popular page will be appear.
5. Navigate to Comment button, under the any topic and double tap.
6. Verify the Voice Over focus is going on Type here to comment on this post text box or not.

Expected:
After activating comment button, voice over focus should move to the Type here to comment on this post text box, so that user will not have to TAB (swipe) excessively to reach to the desired element (comment text box).
Actual:
Voice Over focus goes to Popular back button rather than moving to Type here to comment on this post text box, that is why user has to TAB (swipe) excessively to reach to the comment section for giving comments on the post.

Note:
1> This issue is repro throughout the application, when user double tap on cancel button, then voice over focus is not going on triggering element, it moves on top of the page.
