No Prompt to Save Draft Before Closing Window
Typically, when you're writing a draft and try to close the draft window it will ask if you want to save it first. However, when one of my applications sends data to Thunderbird with prefilled TO, SUBJECT, and MESSAGE fields (and I make no edits to the draft window) it no longer (as of 115 release) prompts me to save the draft when closing the window. If I revise this draft in any way (adding a space to the end of the subject field) it will prompt me when closing.
My workflow consists of saving drafts without any edits needed to the compose window. This used to work fine prior to the 115 release, but now I need to add the space to each draft or hit save and wait 3-5 seconds (to communicate with the server) before I can close the window. Small inconvenience, but is this really the desired action? (imagine someone closes a draft window with data in it, thinking the draft is already saved, and it's simply gone)
