Composer: Redirect cannot scroll message content
I tried out the Redirect feature today, with Evolution 3.38.4 and 3.40.4 on Fedora 33 and 34 (can't test a newer version at the moment). When using the mail "redirect" feature instead of forwarding, there should be a clearer visual indication that the message's body is not editable, and why (possibly).
Currently, when you do that, the webkit view is not editable, not clickable/selectable, and not scrollable. If Evolution needs to preserve the body intact to adhere to some spec (?), I think it should at least allow scrolling up & down (since it doesn't affect the contents) and that it should make it clear visually that the contents cannot be edited. I'm thinking that it could, for example:
- Set the GTK "sensitive" property to False... if that makes it grayed out like it usually does to GTK widgets? Or 50% opacity...
- Alternatively (or additionally), as a clearer visual approach for users, it could show an infobar just above the message body area to inform the user that "This message is a redirection, which allows you to change the To/From and subject line, but not the contents of the message."
