Post isn't marked unsaved on paragraph changes

[pento]

Issue Overview

When editing a paragraph block, the post isn't marked as unsaved until the block loses focus. This allows the window to be accidentally closed, losing any changes in that paragraph.

Steps to Reproduce (for bugs)

1. Create a new post.
2. Add content to the first paragraph block.
3. Click "Save Draft"
4. Add more content to the paragraph block.

Expected Behavior

The save notification changes to "Save Draft", and triggers the "are you sure" message if you press Cmd+W.

Current Behavior

The save notification stays as "Saved", and you can close the tab without a warning that changes will be lost.

There was a PR created some time ago that should fix this problem #2418.

I've experienced this problem too! I was wondering whether it was considered intentional behavior and am glad it's not :)

This should work well now.
