While I press the Back button(RAP Unmanaged) , The records gets saved in Draft without asking ?

[BODHISATTWA__20]

I have created a very simple RAP unmanaged program  with Draft capabilities .Once I click on create(on list page ) and enter the input fields(in object page) .

After that I  click on back button , the record gets saved in draft (which is the expected behavior )---But I was expecting a Dialog Box to pop up and ask , if I want to save keep the draft . (Something that happens in managed scenario)

Am i missing something ??

Something like this
