Steps to reproduce (reproduced in ios + mac client):
Create a bullet list
Copy a shortcut to another note and paste it as one of the list items
Place your cursor at the end of the link (or before) and press carriage return to create a new list item
When you start typing, the new text is green/linked to the shortcut in the previous list item
Expectation is that when you start writing before or after a link, the link should not be "extended" in such a fashion. The above does not happen if you are writing free text, e.g. not in a bullet list.
