After pushing a few pages onto the Navigation Stack, sometimes (seems to be based on how quickly the navigation buttons are tapped) going back does not always return to the proper page.
I tested on Forms 1.3.3 and 1.3.4-pre4. Same results on both.
## Steps to reproduce
1. Open the attached MasterDetail sample project.
2. Set the iOS app as the startup project and launch to a simulator (I did not test on device)
3. Once the app launches, click on one of the rows and then quickly tap the colored "Go to next page" buttons.
4. Click the Back button to go all the way back to the home page with the table view.
Expected result: Will be able to navigate all the way back to hoe page with list view.
Actual Result: Back navigation gets stuck at Page 1.
If not able to reproduce, make sure to click the "Got to next page" button on each page as quickly as possible. If you give it time, the issue does not occur.
I saw this release note in the 1.3.4-pre4 forum thread that I believe this issue may be related to:
"Navigation push/pops will now auto-queue if done before the last one completes. This helps handle some race conditions."
so I made sure to test on 1.3.4-pre1. Updating to that package did not resolve the issue.
I have recheck this issue with Xamarin.Forms version 22.214.171.12433-pre1 and I am also getting same behavior mentioned in the bug description.
This issue seems to not be possible to reproduce on device. There is a consistency issue with the simulator where we are seeing slightly different order of operations on calls. If you have a reproduction on device we are happy to tackle it :)
I have checked this issue with device 5s (iOS version 8.1.2) and am getting same behavior mentioned in the bug description.
Hence I am reopen this issue.
