Post-publish "are you sure" message makes me anxious about whether my changes are save or not

[lancewillett]

Gutenberg version: 1.6.1
WP version: trunk
Other plugins active: Debug Bar, Debug Bar Console

Steps to Reproduce (for bugs)

1. Create a new post
2. Enter a title and some body text (paragraph block, for example)
3. Click the publish button once, then again to confirm

Tested with latest Chrome and Safari 11.0.1 on OS X 10.12.6.

Expected Behavior

I'd expect to not see a warning about unsaved changes after publishing the post. When I next click to close the tab or go to a different link from within the tab I expect it to work correctly.

Current Behavior

When I published the post, and tried to click to close the tab — I was blocked by the infamous AYS alert message like we have in Calypso a lot! (CC @aduth) — “Are you sure you want to leave this page?”

Thanks for the report. Duplicate of #3296, with proposed solution at #3298

Gah! Sorry I missed the other one.

I did make a PR for something else. :)
