[~manovotn] Thanks.

I have confirmed that this issue exists for IE 11,  Firefox 77 and Chrome 84

Just to be clear this is not an issue if these clicks are opened in separate tabs. (CRTL-CLICK). I believe this has to do with the browser canceling the request that is in process.

> NPE occasionally raised in Wildfly 20.0.1 when the response a view is requested repeatedly from the same tab by rapidly double clicking.
> This issue was found while trying to find a reproducer to WFLY-13662 so which could also be failing if some of the request context data is being lost.
