Bindings in delegates attempt to access model data after removal

The attached testcase shows that the QML ListView attempts to re-evaluate bindings after starting a remove animation.

That re-evaluation can include an attempt to access data from a model, such as a QAbstractItemModel, for a row which has just been removed.

That is, the remove animation happens as a result of the QAbstractItemModel::rowsRemoved signal, so there is a 'tension' between the requirements:

1. An attempt in the delegate to access the data while it fades out.
2. The row in the model providing access to that data has just been removed.

The solution could be to cache data retrieved from the model.
