Feature Request: 'Back' button should restore data as defined by user

[Endogen]

Sending a transaction and then before confirming it, hitting the "Back" button will result in resetting everything in the prepared transaction screen except the token that was chosen.
IMO this should really restore exactly what was set up before and not only the token.

1. Initial transaction:
   

2. 'Back' button pressed
   

3. Results in:
   

IMO 1 and 3 should be the same
