It's hard to see what the bug is from the video. At what point does it occur?

Definitely confirmed on:
- gecko: larch:cd99991b8d46
- gaia: camera-new-features:db91804c290f7ed40ba5386a73ae3c23b393000c

Wilson, the problem is that rapidly tapping a menu item (e.g. "HDR") and the back button at the top of the menu a bunch of times gets the menu stuck into a state where "HDR" becomes the _only_ menu you can enter, even if you choose another one (e.g. "Grid").

A couple of observations:
- once the problem occurs, it doesn't go away as long as the menu is open
- rotating to landscape and back does not clear the problem
- leaving the menu DOES clear the problem
- it happens with other menu items, not just "HDR"
- rapidly tapping a menu item and back once doesn't seem sufficient to trigger the problem
- there is no obvious UI corruption aside from the incorrect menu always opening

Unable to reproduce on Helix, Hamachi or Nexus4. Is this a QRD only bug?

Wilson! I can reproduce it on Nexus4 using latest master. 

*Step
1. Click setting menu
2. Click HDR menu
3. Click <HDR of left top (Back button)
4. Repeat 2,3 steps quickly
5. Click Grid Lines -> Menu Lable is HDR

Can Ashish take this issue if you can't reproduce it?
