I'm seeing this as well. Thanks for posting.

Hi. This issue also reproduces in Angular Material 15 (release) when using a customizable theme by using @use '@angular/material' as mat.

I tried on the cold installation of Angular 15 release and then ng add @angular/material with custom theme option.

And as a result I see in console following:

(base) ➜  ang10 git:(master) ✗ ng serve                
✔ Browser application bundle generation complete.
