Steps to Reproduce:
- Type a few paragraphs of plain text in another document (e.g., an e-mail message with rich text turned off).
- Open VisualEditor. Copy and paste your paragraphs into VisualEditor.
- Place your cursor in the first paragraph. Click the list button to turn the first line (only) into a list.
The entire pasted section is indented as if it were a list (a list separated by <br>, not with a bullet in front of each paragraph).
However, when you save the page, only the first paragraph has actually been turned into a list.
