eeschema: unintended junction dots on wire drag

Description

Dragging (G) these two horizontal wires 2 grid units to the left causes junction dots to be added to the vertical wire.

since the right endpoints of the horizontal wires were 2 grid units to the right of the vertical wire, if you merely move them to the left - they would land on the vertical wire and make junctions, which could maybe be counted as okay.

but in this case they are being "extended" and i would not expect junction dots.

also this is obviously a bug since it doesn't happen if you drag them 1 or 3 grid units, it happens when the endpoint would land onto the other wire
