htmx-json does not work with ES module imports

[Massi03dev]

Description:
I'm trying to use htmx-json in a modern ES Modules setup (Webpack) with npm-installed packages.

Steps to reproduce:

1. Install the packages:

npm install htmx.org htmx-json

2. Import them like this:

import 'htmx.org';
import 'htmx-json';

3. Run the project.

Expected behavior:
The htmx-json extension should work and provide attributes like json-text, json-each, etc.

Actual behavior:
The extension does not work. It seems that htmx-json cannot find the global htmx variable, which is not automatically exposed in ES module environments.

Temporary workaround that works:

import htmx from 'htmx.org';

// Make htmx global
window.htmx = htmx;

Promise.all([
  import('htmx-json'),
]).then(() => {
  console.log('All extensions loaded');
});
