ComfyUI-Manager wraps app.graphToPrompt and drops the graph, so every run and
the check before it compiled the canvas: same seeds, nothing of the later marks.
A result that is not the copy's is now made by ComfyUI's own method.
Going back is one of ComfyUI's undo steps, so Ctrl+Z returns to the state left
behind. A save can also open on a new tab, the empty canvas's menu and a + on
the bar keep one, and marks show as saves, runs counted as runs.
