Copy/paste text from (MS Word/MS Outlook) magically creates new newlines.

If I copy text from my Quill editor to Microsoft Word/Microsoft Outlook, then it's works. But if I want copy back these text from Microsoft Word/Microsoft Outlook to Quill editor, then new newlines seem to be inserted into the text. My Quill editor has a 100% width (1800px), and I don't use any specific options (matchVisual, addMatcher, etc.) from Quill.
