Prior to Swagger UI 2.0, the BASE URL field in the footer was determined from a single field (basePath) that was a full URL (e.g. https://example.com/path). In Swagger UI 2.0, this has been split up into three separate fields basePath, host, and scheme.

The result is that when using Swagger UI 2.0 in ActiveDocs, the BASE URL only shows the basePath field (e.g. /somepath) and not the scheme and host.
