The same stuff on my side. It's started after updating Swagger UI bundle and adding attribute "async".

Browser console error
ReferenceError: SwaggerUIBundle is not defined

Environment
Chrome 62, MacOs

Verified
nightly.apin.io, VAMOS site (v0.52)

At the same time If I navigate under incognito mode then it works as expected.
If I navigate directly to url then it works as expected

Closing this as this is very old. Swagger UI to be tested after a big upgrade anyway.
