Expected behavior:

Add a textarea field QA with default settings.
Add an aligned view and in the entry template add the pattern
[[!QA]]
(the template should have both [[QA]] and [[!QA]])

Go to Browse
Press Add a new entry
A new entry form should open and display one textarea for the QA field.
Save
An entry is added and displays nothing for the QA field.

Edit the entry
Enter in the textarea the text:
"Hello, this is a text area field for multi line text."
Save
The entry displays the above text twice (for [[QA]] and [[!QA]])
