I was in the midst of a lengthy edit to my answer to a question, when the question was deleted before I had saved the new text. The webpage was dynamically updated in my browser tab with an overlay with the message "This post has been deleted and is no longer viewable". My entered unsaved text is still visible underneath the overlay. Although it's so faint it's very hard to read, it is definitely still somehow resident in my browser's rendered page.
According to this recent post, deleting a question which has a correct answer is frowned upon. I would hope that deleting while further good faith efforts are in progress are doubly so. So in accordance with suggestions on that thread, I wanted to request the question be undeleted, so that I may finish my edits. But just one problem...
How can I recover my unsaved in-progress text?
Reloading the page and re-initiating the edit on the answer does not pull up the draft (unlike a new answer, which gets drafts saved). Users with 10K rep can see deleted questions and answers, but have no power to see drafts which were never submitted. Right-clicking and using the HTML inspector has not yielded any success either, though I may just need to navigate to the right DOM node.
Are there any other options? Maybe some javascript I can execute in the browser's console? It's Safari, FYI.
Edit: as of today, 30 Nov 2017, it seems that the software has changed. Now when you're editing an answer to a question that's been deleted, the page gets updated with a banner with the message "This question has been deleted - no more answers will be accepted", not an overlay. But you are no longer locked out of your textarea, so if you want to recover your text, you can just highlight and copy. The browser shenanigans are no longer necessary.
