This extension is compiled with the version of Opal used to compile Asciidoctor.js 2. I do not plan to maintain two versions of Asciidoctor Tabs for JavaScript. So either Opal needs to be adjusted to produce compatible code for both Asciidoctor.js 2 and 3, or the extension can only be used with Asciidoctor.js 2. I do not plan to work on this, so someone will need to come forward to do the work.

[mojavelinux]

One possible path forward is that Asciidoctor Tabs 2 will require Asciidoctor.js 3. However, I'm not yet ready to make that transition, so that will not likely happen soon.
