Changing component resets bugreport description

[Germano0]

Upstream clone of Redhat bugzilla bugreport Changing component resets bugreport description (edit)

Description of problem:
I was filling a Fedora bugreport, but I had not yet selected a component.
When I finally have selected one component, bugzilla said "this will change description, do you want to proceed?" I clicked on yes, and it has completely erased my description of the bugreport, making me lose all my work.
This has never happened with past bugzilla versions, so please revert this new behaviour.
Thank you
