To reproduce:
1. Create a new project
2. Create a new script
3. Add a public String List e.g.
{code:java}
public List<string> qotes = new List<string>();
{code}
4. Add the script to any object in the scene
5. Select the object with the script
6. In the Inspector window in the list component add a new element
7. Type \n (you should see that a new line has appeared and \n is gone)
8. Continue typing anything after that

Expected: the text is written in a new line
Actual: the text starts typing between \ and n, and it doesn't go to a new line
