Going back to Prompting after generative Fill Page

Once i go into generative Fill, try out stuff and decide, that i want to reengineer my original prompt and i click "back" in the left hand upper corner, it links me to the Firefly landing page and i have to rewrite ALL of my prompt again. Very annoying, there was a version where this didn't happen.

Pls fix it, or open a second tab once you go into generative fill or something, just ANYthing so you don't lose ur original prompt page.
