bug(OverlayContainer, MatDialog): MatDialog not rendering inside custom OverlayContainer in angular 15 #26542
Description
In Angular 15, if a component is provided with OverlayContainer and overridden to use it as a custom container element, individual overlay elements are not rendering inside the container (), instead is appended to the document body(default behavior).
export class OverlayService extends OverlayContainer{
constructor(
@Inject(DOCUMENT) _document: any,
platform: Platform,
private problem: ElementRef<HTMLElement>
) {
super(_document, platform);
}
protected override _createContainer(): void {
const containerClass = "cdk-overlay-container";
const container = this._document.createElement("div");
container.classList.add(containerClass);
this.problem.nativeElement.appendChild(container);
this._containerElement = container;
}
}
@Component({
selector: 'app-problem',
templateUrl: './problem.component.html',
styleUrls: ['./problem.component.css'],
providers: [
DialogServiceService,
MatDialog,
{ provide: OverlayContainer, useClass: OverlayService },
]
})
Expected behavior:
<body>
<app-problem>
<div>....</div>
<div class="cdk-overlay-container">
<mat-dialog-container></mat-dialog-container>
</div>
</app-problem>
</body>
I was expecting the MatDialog to render inside the custom container as in previous angular versions.
What troubleshooting steps have you tried?
Current behavior(Angular 15):
<body>
<app-problem></app-problem>
</body>
<div class="cdk-overlay-container">
<mat-dialog-container></mat-dialog-container>
</div>
