Steps to recreate:

1. Navigate to an existing talk page
2. Create a new topic
3. Tap Next to view the message preview
4. Tap back

Expected Result:

• The talk page message editing state appears, with what I had already typed
• If I navigated back again the edit state, I would see the confirmation if I'm sure I want to exit and lose my draft.

Actual Result:

• Dialog box asks you "Are you sure you want to exit?" The subject and content will not be saved
• Choosing Yes brings me back to the talk page and I am not able to edit my message
