The deleted row remains in the model after being submitted. Internally, 
selectRow() refreshes just the row that was submitted. This gives you 
the opportunity to revert or retry a failed delete operation.

As pointed out by Karl, select() resets the whole model. However, 
instead of connecting this to the rowsRemoved() signal, it might be 
better to reimplement selectRow() to make it call select() if that is 
what you want.

Another possibility is to use OnManualSubmit edit strategy, which always 
uses select() (rather than selectRow()) after submitting.
