Testing #77427

If I clear out the input field and press "Save", the edit is thrown away. I would expect that either an empty string is inserted into the array or the item is removed.

To repro:

• add a new string array setting foo, press "OK" to commit it
• now click on the pencil to edit the item foo. clear out all of the characters so the input field is empty, click on "OK" to save

Result: foo is reverted back into the input field.

Expect: Either the element is deleted or an empty string is persisted to the array. I don't know exactly which I prefer.
