Inappropriate behavior using Explore setting

[kilroyFR]

Whatever i can set on URL defined in EXPLORE field (discoverpath), when i am using 'TryOut' test button, it's always the Base Url that is used
(in the example : apache-apis1-septa.valm:9004)

When using SwashBuckle i did not have this behavior, the path entered in EXPLORE (discoverPath) is used when 'TryOut' is used.
Is this something made on purpose ?

Thanks !
