This is mostly working, but there are some issues with the minified js. Currently, control callbacks are handled with HTML attributes like onclick or onchange. When the js is minified, the function names are minified, but the function names used in the event attributes are not. This breaks the page :/

RE the HTML event attributes not using the minified function names, we're going to skip this for now, and will be fixed when we refactor to Vue components.
