We are currently using JCE Mediabox popup modals with Gantry 5 Joomla templates (which allows custom scripts and CSS to apply to individual pages).

When a modal popup link is created, the page within the iframe forces "?tmpl=component". This results in custom javascripts and even CSS to be removed from the modal popup's page. This occurs even when a page for Joomla extension (not article) is viewed.

But when a link within the modal popup is clicked, the "?tmpl=component" is not applied anymore.

Is there a way to stop JCE Mediabox from adding "?tmpl=component" to the modal's page? I understand the need for it when viewing articles, but it does that to extensions' pages as well.

Some templates (eg Gantry5) allow you to remove certain parts (eg sections, header, footer, modules,etc) off specific pages. We don't need Joomla's component-only view as it's very limiting.

By forcing ?tmpl=component, every module gets removed and we can't have a custom module (or even custom css) in the modals when used to open other extension's pages, for example. There's no way around it.
