Answering 'No' to PDB Autoassociate dialog doesn't import PDB files

If you drag-and-drop a pdb file onto an alignment containing sequences with the same name, Jalview offers to associate the pdb files with matching sequences. Saying 'No' should result in the files being loaded as new sequences in the alignment - but in 2.10.3 it doesn't.

E.g. drag and drop the same PDB file - first onto the desktop, and then onto the alignment that opened when you dropped it the first time.
