### Additional context

_No response_

Start by reproducing the problem with Graph connecting.router.args.padding set to 10 and an EdgeTool segments tool, then drag the tool to observe the malformed line. Trace the routing and line-drawing entry points involved in that configuration; done means dragging the segments tool keeps the line displayed normally.
