Okta Sign-In Widget + Angular Material components changeDetectorRef

I’m trying to add okta sign-in widget to myAngular 7 application. I noticed it break some of the existing functions, such as it does not work with the Angular material2 autocomplete component.

Originally, every key stroke will trigger a refresh of the drop down panel, but with the okta login widget, I have to refocus the input panel to trigger an update to the drop down panel.

I was trying to understand the changeDetectorRef, what is the impact that Okta Sign-In widget brings?
