When you paste multi lines text in VE coming from a simple text editor :
- VE renders it visually as a multi lines text
- VE save it as consecutive lines, resulting in fact in a single paragraph (if you edit again the page in VE, it will be displayed as a single paragraph with the arrow symbols showing there are carriage returns in the text)
The display is totally inconsistent with the actual result.
