@if Syntax Not Rendering Content in Angular 18

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):
"@angular-devkit/build-angular": "^18.2.4",
"@angular/cli": "^18.2.4",
"@angular/compiler-cli": "^18.2.4",
"@angular/animations": "^18.2.12",
"@angular/cdk": "^18.2.13",
"@angular/common": "^18.2.12",
"@angular/compiler": "^18.2.12",
"@angular/core": "^18.2.12",
"@angular/forms": "^18.2.12",

"@angular/platform-browser-dynamic": "^18.2.4",
"@angular/router": "^18.2.4",

Describe the bug
The @if syntax introduced in Angular 18 is not rendering the content as expected. Although the conditions are valid, the HTML elements within the @if block do not render in the UI. However, when I remove the @if block, the UI elements appear as expected. Could you please give me advice to fix this issue? Thanks.

To Reproduce
Create an Angular 18 component with the following template:

@if (cvDetail && cvDetail.id) {
  <div class="right-content">
    <div>
      <div id="toc-target">
        <div #htmlToc class="toc-content"></div>
      </div>
      <div id="toc-target-no-water-mark" #htmlTocNoWaterMark>
      </div>
    </div>
  </div>
}

export class ExampleComponent implements OnInit, OnChanges {
  @Input() cvDetail: any; 

  @ViewChild('htmlToc') htmlToc: ElementRef | undefined;
  @ViewChild('htmlTocNoWaterMark') htmlTocNoWaterMark: ElementRef | undefined;
  constructor() { }
  ngOnInit(): void {
  }
  ngOnChanges() {
    if (this.cvDetail) {
        if (this.htmlTocNoWaterMark) {
          if (this.htmlToc) {
            this.htmlToc.nativeElement.innerHTML = '';
          }
          this.htmlTocNoWaterMark.nativeElement.innerHTML = this.cvDetail.body ? this.cvDetail.body : '';
        }
    }
  }
}

Expected behavior
value of this.cvDetail.body, example is '

sample (Red font, bold, underlined)

' will be rendered in the UI
