ADDITIONAL SYSTEM INFORMATION :
Windows 10, Open JDK 11.4

A DESCRIPTION OF THE PROBLEM :

Basically we have an ADFS authentication URL which loads in JavaFX (JDK 8u91) WebEngine and which takes to ADFS federation login page. So on click of 'Active Directory' option,
the application will exchange the auth code for an access token and token will be returned back to application either as query param/ java.net.CookieManager with key as'ADFS-Crendential'.

But when we migrate the same code to OpenJDK 11.0.4/javafx-sdk-11.0.2 versions, the re-direction of auth server is not happening(On click of 'Active Directory' option, the re-direction of url is not changing that is webengine.getLocation() is remain same and a blank page is rendering.

I monitored logs using webengine listeners as well, the URL is not changing).
 
Note: Same issue in JDK 8u202.
