Actual behaviour:
When an empty card is displayed in the reviewer window, ‘answering’ the card by selecting an interval (e.g. ‘Again’) will skip to the next card, however the empty card message will stay in the reviewer window. This way it is actually possible to review the entire deck without seeing the actual card.
Expected behaviour:
After assigning an interval to en empty card, the reviewer should proceed to the next card in the queue and the empty card warning should disappear.
