Steps to reproduce

1. Create a new Travel Standard Page (just for verification)
   1. after clicking next the page dialog opens where you can enter all the information
2. Remove the dialog on the standard template, so that it gets the dialog from the prototype (https://demo.magnolia-cms.com/.magnolia/admincentral#app:resources:edit;/travel-demo/templates/pages/standard.yaml:edit), dialog to remove:

   dialog: mtk2:pages/basic

1. Create again a new Travel Standard Page
   1. The page is directly created without the dialog in
      1. 1.a. In this case the dialog is not getting merged from the prototype. This is the bug or missing implementation from Magnolia side we are facing.
2. When you open the newly created page and click Edit page properties the inherited dialog from the prototype is showing up again follow the prototype definition.

Summary: On page creation the prototype concept isn't working for the dialogs.
