Users should not be able to select "English > English" in the language selector for suggestions since it does not make sense.

In order to prevent that, we propose the same approach used for the new translation dialog selector (swapping the values to avoid the conflict):

• Make sure that initially the source and target languages are different.
• If the user tries to change the source language to the target value, swap the language values. That is, if the initial state is "English>Spanish" and the user selects Spanish as source, the result will be "Spanish>English".
• If the user tries to change the target language to the source value, swap the language values. That is, if the initial state is "English>Spanish" and the user selects English as target, the result will be "Spanish>English".
