Checked live on EasyEDA Pro 3.2.209 with easyeda-mcp-pro 1.8.0. The server's net listing takes parts and flags from every loaded page but wires from the focused page only, then joins them by coordinates. With the layout_tree page closed, pin U4.11 drops off the V_LED net again. The author first blamed EasyEDA, traced it to the bridge, and drafted an upstream issue and PR without posting them. The workaround stays in place. An agent reading this board gets a different netlist depending on which tab a human left open.
