Web demo crashes upon selecting "Custom HTML" interface

Steps to reproduce:

I'm not sure what the expected behavior of this is, but the demo currently crashes and will not recover upon selecting a different INTERFACE from the drop down:

The demo is currently at version 1.9.0 at the time of writing.
However, it suffices to reload the page to restore normal behavior.

Thanks, looks like this was a problem with the new site setup / demo server! Fixed it and the HTML example should now work as expected again :slightly_smiling_face:
