http siteurl on https site will break widget

[pc-coholic]

If a wordpress' siteurl is set to http://foo.bar, the pretix-widget will not be properly display in the frontend only due to mixed content loading issues.

The fix is easy enough (unless the site owner is using wp_multisite) by going to /wp-admin/options-general.php and updating the siteurl to the proper https-version.

But I do still feel like there is something weird going on and we should have a look at this...

Everything else that is piped through the likes of wp_enqueue_script seems to properly detect that the script is running on an https-page; even when siteurl is set to http (such as wp-content/plugins/pretix-widget/assets/css/style.css) - it seems to only/mostly (?) affect the wp-content/uploads/pretix-widget/cache/randomhash.js...

Correction: This affects at least pretix-widget-frontend-css and pretix-widget-frontend-js.
