Issue Summary:

When a Connect iframe is present within an embedded Confluence page on a site with a custom domain, the Connect iframe fails to load. This is because the hostOrigin of the iframe does not match the custom domain of the site.

Steps to Reproduce

1. Navigate to a site with a custom domain.
2. Navigate to/embed a confluence page with a Connect iframe present.

Expected Results

The iframe loads.

Actual Results

The iframe does not load. Checking AP._hostOrigin in the console (within the context of the iframe) will show the canonical URL rather than the custom domain.

WorkaroundCurrently there is no known workaround for this behavior. A workaround will be added here when available
