- Fix (Embedded editor): (Though embedding cross-origin iframes apparently

only working now in Chrome if same origin or if https?--at least not
  localhost of different ports), PDF export has been fixed (we download the
  PDF to workaround data URI limitations in Chrome)
- Fix (Embedded editor): Avoid using same origin shortcut if there is no
  global available to use (e.g., if using the modular editor)
- Fix (Embedded editor): Add events only after load is complete and
  svgCanvas is available; also log blocked error objects
- Enhancement: For PDF export, switch Chrome by default to "save" `outputType`
- Docs (JSdoc): Denote optional arguments
