When embedding a Web Content Display portlet in theme header and render a content using a user-defined structure/template, cannot submit a form which does not stay in a portlet (Update password form).

Steps To Reproduce:

• Create a Structure and Template with a Text input field.
• Create a web content article with this Structure and Template.
• Deploy the header-theme.war (or header-theme-73x.war for master) and apply this theme to the portal. It's a theme in which Web Content Display is embedded in the header tag.
• Select the web content article to display in embedded portlet.
• Create a new user in the portal and login with this new user. In the user completion process, when you try to update the password.

 Expected result:

• User can update password and going forward with next step.

 Actual result:

• User stuck at update password form.
• UI inspecting shows that the form is using the portlet namespace from Web Content Display portlet.
