@Jeff I just tried it and also see the same behavior Julien reports.
The original behavior was working like Julien's point 2 in #5:
1) after clicking the context menu selection of which bus member to unfold, you have a ghosted bus entry, wire(s) to the cursor, and a label at the cursor
2) after first click, the bus entry, wire(s), and label are fixed, and you drop into wire drawing mode to continue the wire
