Error 'Dom7 is not defined' when starting Framework7 - Vue app with Webpack

I just follow the instructions in the official page: clone the repo, install node dependencies and run. But once I run the npm run dev command, when I open the app in the browser I get the following error:

> Uncaught ReferenceError: Dom7 is not defined
>     at framework7.js:14213

Can anyone help with this?
