Text pasted from MS Word to RichText doesn't keep newlines in certain formatting types.
- Prepare some chunk of text in MS Word and insert new lines (Shift+Enter) in between e.g. "one line text [Shift+Enter] another line of text ...".
- Paste it in the RichText Editor into one of the following: itemizedlist, orderedlist, table, heading.
- Hit "Publish".
- Visit published content in the admin panel.
Result: All the newlines are gone and the text is visible in one line.
