💻 Code

import ts from 'typescript';

const filename = 'example.ts';
const code = `
/** 
 * 
 * @usageNotes
 *
 * Use \`afterNextRender\` to read or write the DOM once,
 * for example to initialize a non-Angular library.
 *
 * ### Example
 * \`\`\`ts
 * @Component({
 *   selector: 'my-chart-cmp',
 *   template: \`<div #chart>{{ ... }}</div>\`,
 * })
 * export class MyChartCmp {
 *   @ViewChild('chart') chartRef: ElementRef;
 *   chart: MyChart|null;
 *
 *   constructor() {
 * 
 *   }
 * }
 * \`\`\`
 */
class Foo  {};
`;

const sourceFile = ts.createSourceFile(
  filename,
  code,
  ts.ScriptTarget.ESNext,
  true
);

const visitNode = (node: ts.Node) => {
  ts.forEachChild(node, visitNode);
  const tags = ts.getJSDocTags(node);
  if (tags.length) {
    tags.forEach((tag) => {
      const comment = tag.comment!.slice(1) as any;

      console.log(
        '> ',
        tag.tagName.getText(),
        ' | ',
        ts.getTextOfJSDocComment(comment)
      );
    });
  }
};

ts.forEachChild(sourceFile, visitNode);

🙁 Actual behavior

We get 2 distinct tags:

>  usageNotes  |  se `afterNextRender` to read or write the DOM once,
for example to initialize a non-Angular library.

### Example
```ts
>  Component  |  {
selector: 'my-chart-cmp',
template: `<div #chart>{{ ... }}</div>`,
})
export class MyChartCmp {
>  ViewChild  |  'chart') chartRef: ElementRef;
chart: MyChart|null;

constructor() {

}
}

🙂 Expected behavior

Only one tag should be extracted : usagenotes

Additional information about the issue

No response

Inizia con l’API getJSDocTags e riproduci il comportamento usando l’esempio StackBlitz nell’issue. Traccia il modo in cui il commento JSDoc viene analizzato intorno al fenced code block, quindi verifica che venga estratto solo il tag usageNotes e che il testo simile a un decoratore venga ignorato.
