Unpublished Changes message does not appear when modifying task lists and drop downs when Collaborative Editing is ON

Issue Summary:

Shared drafts do not show Unpublished Changes warning message when task lists or drop downs are modified.

Steps to Reproduce

1. Currently, in Confluence, the shared drafts do not show the Unpublished Changes warning message when tasks are modified (checked/unchecked) after modifying in edit mode without saving the page. This also occurs with tasks or drop down lists in certain add-ons (Easy Dropdowns as an example).
2. The Unpublished Changes warning message only appears when text is added during an edit without saving the page.
3. Attached below is the video of the testing where Unpublished Changes only appears when texts are added.

Expected Results:

It would be better if Confluence gives the same warning message Unpublished Changes when tasks or any changes are being modified. For customers who have a heavy reliance on task lists or certain add-ons, this can make the page information unreliable. This is not mentioned in our documentation: How do Drafts Work.

Actual Results:

There is no warning about Unpublished Changes for certain specific changes made on pages.

This is created based on a feature request: https://jira.atlassian.com/browse/CONFSERVER-59676 because I believe this behavior is a bug and should not be a feature request.
