possibility to create a duplicate way with split dialog

[Klumbumbus]

from ​http://forum.openstreetmap.org/viewtopic.php?id=52671

What steps will reproduce the problem?

1. Download a way with minimum 4 nodes. (The way needs an OSM-ID otherwise the dialogue won't pop-up.)
2. Mark one node and hit "P" to split the way.
3. Ignore the dialogue. (don't click someting)
4. Mark a second node and hit "P" again.
5. a second split dialogue appears.
6. click OK in both dialogues
7. the section between the previously selected nodes is part of both new ways an therefore they overlap
