Pasting multi-level lists strips formatting

Issue Summary

When pasting multi-level numbered or bullet lists in Confluence New Editor, the formatting is stripped due to Confluence auto-format.

Steps to Reproduce

Use Bullet List.docx as an example.

Paste in New Editor Example

Paste in Old Editor Example

Confirmed that a similar behavior occurs when pasting from Pages application instead, but not from other applications, such as Notes on macOS.

Expected Results

The original formatting should be retained when pasting into the new editor, much as it does when using Paste and Match Style.

Actual Results

Confluence's new editor does not retain the formatting when pasting a list. Appears that this may be due to auto-formatting.

Workaround

Paste without formatting, or import as Word document:

Paste and Match Style

Import Word Document Old Editor

Import Word Document New Editor

Notes

Paste from Notes application

Paste Tabbed Lines Instead
