I've had an interaction with a Gutenberg user that experienced content loss while using the editor. Here are the potential steps to reproduce the issue.

• Write a long post (and scroll to the bottom to potentially hide notices that appear at the top of the page);
• Cut the internet connection or let it sit for a while.
• A notice shows up but not visible enough.

At this point, the content loss happens. It's not really clear what caused it. The notice might have been dismissed, switching to writing other posts/tabs could be a factor too.

Expected Result

• Ideally, the content loss doesn't happen as we have local storage saving.
• Also, the notice is not visible or clear enough, it should be more prominent and indicate the potential content loss. Maybe it should be non-dismissible.
