Hi!

Thanks for the repro and the bug report.

The bug is because the indentation state GRAPH_PRE_ROOT is being triggered, due to "R" being a root. What this state does is add a new row to connect the indentation:

Then it pushes everything to the right.

The fix should be that the rendering of the graph is the same with the indentation or without it, as there is nothing ambiguous in this case that needs it.

I think I may be able to see how to fix it tomorrow, but I'm quite busy until next week.
