The notification is called like this in tenant-settings.component.ts.
tenant-settings.component.ts
this.notify.info(this.l('SavedSuccessfully'));
And this is what it looks like in the browser (Google Chrome, Version 74.0.3729.108 (Official Build) (64-bit)).

We ended up adding the below css to src/angular/src/styles.css to fix this issue.
.swal2-popup.swal2-toast { padding: 12px 16px 12px 0px !important; }
