'rand' example does not work #9

The example for 'rand' specifies font-feature-settings: 'rand' 1. In HarfBuzz’s implementation, that requests glyph 1 from the alternate substitution rule. To enable randomness, set the value to 255. However, since HarfBuzz enables 'rand' by default, it would be even better to not use font-feature-settings at all, and just let it work automatically.

This issue affects many of the other special features as well, "init" 1 will cause HarfBuzz to apply it to all of the text unconditionally which makes the examples look wrong. If you want to enable init and disable everything else, disable all other features except it.
