Pressing 'Done - Nuke the plaintext' does nothing

On the website hitting the done button after encrypting and signing a message only removes the button and nothing else happens. I can go back to the encrypt a message menu by pressing edit and write a new message.

I believe hitting this button should have removed the plain text and returned to the encrypt a message menu but this doesn't occur.

Reproduce the flow on the website by encrypting and signing a message, then pressing “Done - Nuke the plaintext.” Start by tracing that button and the edit action back to the encrypt-a-message screen. Done should remove the plaintext and return to the encrypt-a-message menu, rather than only removing the button.
