Theme embedded portlets cannot be configured in Content Pages

Issue

• The portlet cannot be edited.
• Steps to reproduce:
  1) Setup 7.2 vanilla with latest FP, start the server
  2) Create a minimal theme 'my-liferay-theme' with yo liferay-theme
  3) cd into the root folder of the theme and run gulp build
  4) Copy over portal_normal.ftl from my-liferay-theme/build/templates into my-liferay-theme/src/templates (create the templates directory if missing)
  5) Edit my-liferay-theme/src/templates/portal_normal.ftl and add this snippet in the content section:

  <@liferay_portlet["runtime"]
  portletName="com_liferay_journal_content_web_portlet_JournalContentPortlet" />

  6) Compile the theme with gulp build and deploy my-liferay-theme/dist/my-liferay-theme.war to liferay/deploy folder
  7) Create a Content Page in Liferay
  8) On the Content page, at the right-side toolbar, navigate to Look and Feel > Define a specific look and feel for this page > Change Current Theme > My Liferay Theme > Save
  9) Web Content Display onto the page can be seen. Hover the mouse over it to attempt editing it (e.g. selecting a web content to be displayed)
  Expected Behavior: The portlet to be editable
  Observed Behavior: A message on the interface will pop-up and it won't be possible to change the configuration.

  This area is defined by the theme. To change theme settings go to the Look and Feel configuration in the sidebar.

Environment
