Error when using viewport 'snap': TypeError: Penner__default.default is undefined

[xbgbtx]

I get the following when I use the 'snap' funcion.

Uncaught (in promise) TypeError: Penner__default.default is undefined

Something not initialized in these lines?

    function _interopDefaultLegacy (e) { return e && typeof e === 'object' && 'default' in e ? e : { 'default': e }; }

    var Penner__default = /*#__PURE__*/_interopDefaultLegacy(Penner);

Am I missing a plugin for these Penner functions?

This is my project: https://github.com/xbgbtx/L-Systems

I am including the viewport lib using html script tags with the latest github release.

Initializing pixi / viewport is done here: https://github.com/xbgbtx/L-Systems/blob/88e4d4b753da8c94fce6610375a86cee5290e8bb/lib/pixi_app.js#L5-L59

Using:

• PixiJS 6.1.0 - WebGL
• pixi-viewport - v4.32.0

Including penner.js from https://github.com/bcherny/penner worked for me. Just make sure that Penner (with capital P) is defined globally (the library defines it as window.penner) So you might need to rename the variable.

Hope that helps.
