WARNING in Entry point '@angular/material' contains deep imports into 'C:/ui/node_modules/rxjs/Subject', 'C:/ui/node_modules/rxjs/Subscription', 'C:/ui/node_modules/rxjs/observable/fromEvent', 'C:/ui/node_modules/rxjs/observable/merge', 'C:/ui/node_modules/rxjs/observable/of', 'C:/ui/node_modules/rxjs/Observable', 'C:/ui/node_modules/rxjs/observable/throw', 'C:/workspace/ui/node_modules/rxjs/observable/forkJoin'. This is probably not a problem, but may cause the compilation of entry points to be out of order.
