🕗 Version & Regression Information

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

Start with the getJSDocTags API and reproduce the behavior using the StackBlitz example in the issue. Trace how the JSDoc comment is parsed around the fenced code block, then verify that only the usageNotes tag is extracted and the decorator-like text is ignored.
