XPage 'publish' option doesn't adhere to SCXML 'publish' hint

In case of a customization in SCXML, where the 'publish' option is disabled for self-changed documents, this works OK for normal documents, in the content editor, however this doesn't work for xpages in the Pages menu (Experience Manager).

Reproduction

• On a project with XPages, (e.g. public demo), replace scxml with scxml-definitions.xml
• Observer the Publish option is not enabled for self-changed documents
• Add an XPage, view in channel
  Expected: 'Publish' option is not enabled
  Actual: 'Publish' option is enabled

Analysis:
The publish option doesn't listen to "publish" hints (from SCXML) but to "publishBranch"
There's a mapping in org.hippoecm.hst.pagecomposer.jaxrs.services.component.XPageContextFactory which got changed in CMS-13746 (14.4.0) to do that:

After giving it some more thought I think all that is needed is to use the workflow action "publishBranch" for XPages.
