extradoc: editing text inside a list item fragments the list on push

[sripathikrishnan]

Bug

Editing the text content of a single numbered-list item causes the list to fragment on push. The edited item switches from numbered to bulleted, and subsequent items restart numbering.

Repro

Document: 1YKyqqH8wZa3kSnoBEdlwAumI94gRivSsZB1qvc9y4CA (sample3, Tab 1).

Pulled list:

1. Headings
2. Lists
3. Links
4. Images
5. Tables

Edit only the text of item 4: Images → Images and Figures. Push. Re-pull:

1. Headings
2. Lists
3. Links
- Images and Figures     ← became a bullet
1. Tables                ← numbering restarted at 1

Expected

Since only the text of an existing list item changed, the push should emit a simple paragraph-text edit (delete + insert within the item), leaving list structure untouched. No list operations (createParagraphBullets / bullet preset changes) should be generated.

Notes

• Other edits in the same push (plain paragraphs, simple table cells, HTML table cells) round-tripped cleanly — the bug is specific to in-place text edits of list items.
• Found during QA of the pull/push workflow on 2026-04-10.
