DicePicker results in exception

[wcroteau]

NOTE: This may be a case of mis-use or invalid configuration. The documentation is notably sparse regarding how to configure the DicePicker so this is my "best guess" based on the documentation as written.

When I attempt to include the dice-picker addon it results in an error:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'target')
    at new dicePicker (dicePicker.js:59:27)
    at index.js:107:22
dicePicker @ dicePicker.js:59
(anonymous) @ index.js:107

As a setup all I've done is attempt to create a new DickPicker when the Box.init() promise resolves - exactly the way DisplayResults is created...

Box.init().then(async (world) => {
   ...
   const dicePicker = new DicePicker();

   const Display = new DisplayResults('#dice-box');
   ...
});

The error seems to indicate that the target is undefined (despite the documentation indicating that it defaults to document.body) however I've also tried setting the target via options to { target: 'body' } with the same results.

Finally, I've also tried targeting a custom element: {target: '#picker-div'} and in this case the picker DOES display without exception however it is not relative to the target element I specified (in this case I would have expected it to display within the div I specified so that I can control placement and visibility however it seems to be positioned absolutely on the page... (perhaps a separate issue?) similar to the way Dice-Box gets generated within its target (again so that I can control when/where it is displayed...)
