Describe the bug

The Show Route Guides button draw the correct route guides of a net. However, when using draw_route_guides the via stack is missing for IO pins and instance pins.

Expected Behavior

Both methods should draw the same guides.

Environment

N/A

To Reproduce

Under src/grt/test, run openroad clock_route_cugr.tcl. Then open the GUI, select the net clk and click on the Show Route Guides button on the Inspector.

Then hide the guides on the same button and run the command draw_route_guides "clk". The mismatch between them will be visible.
