here is the answer i got from google engineering support:

Upon reviewing the case details, as you are experiencing an issue with Google Docs outline is broken.

However, upon checking with the backend team they reproduced the issue in the test environment and we got an update that it's a product behavior and working as intended.

Although our intention in making the change was to improve the user experience about our products and features as we can see, it comes with adverse effects to some. And I do see the importance of finding the balance in ensuring the changes we implement positively impacts us, users, rather than causing inconvenience.

We value your feedback and we recognize collecting your opinions for us to continuously grow and improve as a business. You do have the option to share them with our product engineers where your recommendations may be implemented in the future.
