Fix site Javascript failing to load in Seamonkey, Palemoon, and other
older browsers.
The @alpinejs/morph library uses public instance fields, which is ES2022
syntax not supported in older browsers. This is the code:
var DomManager = class {
el = void 0; // `el` is a public instance field
}
// => SyntaxError: bad method definition
The fix here is to separate the Alpine code into a separate bundle so
that a failure to load it doesn't cause the rest of the site's
Javascript to fail to load.
A better fix would be to either transpile the @alpinejs/morph library to
ES5 (which seems difficult to do in webpacker), or to fix the library
upstream to not use this syntax.
