Uncaught error for qmol get_svg()

[atfera]

Describe the bug Hi, I have an Uncaught error when using get_svg or draw_to_canvas for this smarts [nH1] with qmol. [n&H1] is the same smarts but for this one drawing works.

To Reproduce

1. Go to https://www.rdkitjs.com/

  var smarts = "[nH1]"; 
  var qmol = RDKitModule.get_qmol(smarts);
  var canvas = document.getElementById("canvas-2");
  qmol.draw_to_canvas(canvas, -1, -1);

4. See error in console

Expected behavior Drawing should be working for the 2 smarts (should be the same smarts https://www.daylight.com/dayhtml/doc/theory/theory.smarts.html). I don't have the same issue with rdkit python.
