[AEM] Multiple domain support for Manage Publication Preview

[#1]

Request for Feature Enhancement (RFE) Summary:	Multiple domain support for Manage Publication Preview
Use-case:	My customer APG would like to be able to preview the website in AEM that contains links to multiple domains. The Publication Preview functionality is not following the externalizer configuration to be used properly (screenshot of externalizer domains used below).
Current/Experienced Behavior:	It is possible to set multiple domains in the externalizer configuration, but only 1 domain is respected in the Publication Preview functionality, resulting in errors in the links when previewing the website (see 'part 2' screenshot below). The impact of multiple domains not being support in the Publication Preview functionality is that it is impossible for APG to properly preview their websites and use this feature properly to identify potential issues.
Improved/Expected Behavior:	An out of the box solution to support multiple domains for links in the Publication Preview would enable APG to preview their websites properly in AEM.
Environment Details (AEM version/service pack, any other specifics if applicable):	AEMaaCS feature release 2025.2.0, maintenance release 19823
Customer-name/Organization name:	APG Groep N.V.
