I'm using !include to include a YAML file with a tab definition which includes a YAML list of fields.

When I use the old !include[space] syntax, the field order remains the same.
When I use the new !include: syntax, the field order is rearranged.

The field order should not change.

To reproduce:

• load light module attached as a zip.
• In page editor, create a page with walkthrough template.
• Add a "c" component to the page.
• Try changing the which include syntax is used in the /walkthrough/dialogs/components/c.yaml file.

Note that if the YAML snippet with the list of fields is defined as a map instead of a yaml list, then the fields do not get re-ordered. (You can use the myCoolTabMap.yaml file to test this)
