Delete trace segment deletes many other traces
In v0.9.9, when I click on a segment of a trace and delete it using the x key, it deletes many other traces on the board.
From what I can tell, it deletes every trace on the same layer (including vias) that has a segment below the segment I wanted to delete. So if I delete a segment that's near the top of the board, it will delete almost every trace on the layer, but if I delete one near the bottom, it may only delete half the traces (those for which part of the trace is below the one I selected).
The screenshots show the segment I selected, and what happens after I delete.
