[PatternFly] PatternFly Next browser support?

[Stan Silvert]

What browsers will PatternFly Next support?

Our app is using Angular 2+.  Its support list is here:

https://angular.io/guide/browser-support

BTW, React's browser support is not as definitive:

https://reactjs.org/docs/react-dom.html#browser-support

Since we are planning to move to PatternFly Next as soon as possible, I 
need to find the intersection between PF Next and Angular.
