Placeholder texts are not being rendered while filling variables on templates with the new editor

Issue Summary

On the new editor, if we create a page using a template/ blueprint that has both variables and instructional texts (placeholder text), the instructional text won't be rendered on the screen to fill the variables

Steps to Reproduce

1. Create a page template with variables and placeholder texts on it
2. Select to create a page with this new template

Expected Results

Placeholder texts should be rendered when filling the variables

Actual Results

Placeholder texts are hidden when filling variables:

This is the template	This is the screen to fill the variables

Workaround

Currently the available workaround is to first fill the variables and then proceed with the page creation, where the placeholder texts will be shown.
