1. Select a message with HTML part that requests receipt notification. You will notice "This message asks for a return receipt." between message list and prevew pane. 2. Select HTML component of the email from the list of message parts to display the HTML in HTML viewer. Error: The notification disappears. The only way to make it appear again is by selecting another message and then re-selecting the message, or closing and re-opening the preview. Desired behaviour: The return receipt notification should not disappear. PS: I have seen this on Win32 build but I am guessing it's a problem with all versions, and therefore I'm posting it here. Please move this to Win32 section if that's not the case.
This is true, but this isn't a bug, that's how our plugin architecture work. If you look closely, selecting an HTML part removes the mail headers, too. I don't think we'll change that.
I wanted to update this to "FIXED" because somewhere along the way, it started behaving the way it should -- selecting individual message parts does not hide the notification of return receipt request.
