As a user without translator rights, it is possible to insert text from the translation helpers, even though the translation editor text area is read-only.
Steps to reproduce:
1. Go to URL as anonymous user
2. Click "Admin" in row 6-7.
Observed:
I. Translation editor opens
II. Messaging is "You need permission to translate messages."
III. Textarea is read-only.
3. In the translation helper area, click "Use as translation" below "Beheer"
Observed:
IV. String is inserted in editor, which remains read-only.
Expected:
V. Nothing should happen (or something else, but at least no string insertion in the editor).
