• Click edit on a section and cut some text from it.
• Save the edit.
• Then click edit on a section below the one you just edited.
• Paste the previously cut text into this section.
• Try to save the new edit.

What happens?:

You receive an edit conflict with yourself, even though you are the only editor making changes sequentially.
