STR:
Expected result:
In both edit and view collection - "Add-on note" is displayed - as mentioned here
Actual result:
There's an inconsistency between the two pages - Edit collection displays "User comment" instead of "Add-on note".
Notes:
This issue is reproducible on AMO dev with FF60(Win10).

This was intentional, but perhaps should be re-evaluated. There are two different contexts, hence it may be that the two headings are appropriate.
The use of the "User comment" heading in the edit form is based on the mockup at https://github.com/mozilla/addons-frontend/issues/4578#issuecomment-393260468.
@pwalm Do you want to keep the different headings, i.e., "Add-on note" when viewing a collection and "User comment" when editing a collection, or should we make them both the same?
"Leave a note" in edit mode.
"Collector's note" when the note is being viewed by either the creator or a user.
