isPath property not syncing, When user clicks "Show the path" between two nodes, the UI highlights the path visually, but the exposed data doesn't include isPath: true because the canvas doesn't know about this application state change.

Node drag positions not updating, When user drags a node to a new position, the canvas renders it in the new location, but the exposed data returns the old x/y coordinates because those values don't update after drag.

visible property not syncing, When user hides/unhides nodes via the element menu, the UI updates correctly, but the exposed data doesn't reflect the new visible: false/true state because the canvas filters out invisible nodes before receiving them and doesn't track visibility changes.

I just checked the Canvas tests only, and there are the bugs I listed above. check the rest of the tests
