When creating a tag and selecting a subpage of the demo site, if this page has variants, those variants don't get the tag included even though the "Insert in subpages" option is checked.

Steps to reproduce:

1. Select the page /travel/about
2. Create at least one variant of it
3. Create a marketing tag, select /travel/about in the page tab and be sure to check the "Insert in subpages" option.
4. Publish variants and tag

The result is that:

• "About" page gets the tag inserted
• Any subpage like "Company" gets the tag inserted
• Variants of "About" don't get the tag inserted

Nevertheless, if I create the tag for the whole site "travel" with "Insert in subpages" option checked, it will include the tag in all variants no matter at what level of hierarchy.
