This is faulty behavior

💻 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

Commencez par l’API getJSDocTags et reproduisez le comportement à l’aide de l’exemple StackBlitz fourni dans l’issue. Suivez la manière dont le commentaire JSDoc est analysé autour du fenced code block, puis vérifiez que seul le tag usageNotes est extrait et que le texte ressemblant à un décorateur est ignoré.
