How to reproduce:

• open the add note with the type "cloze"
• leave the "text" field empty
• enter a cloze in the "back extra" field

Expected:

• The warning stating that the cloze should not be in this field

Actual:

• nothing

Note that if you add some content to the "text" field, then the warning appear. Which is not very intuitive, given that this content is not related to the warning
