🕗 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

Bắt đầu với API getJSDocTags và tái hiện hành vi bằng ví dụ StackBlitz trong issue. Theo dõi cách chú thích JSDoc được phân tích xung quanh fenced code block, sau đó xác minh rằng chỉ tag usageNotes được trích xuất và phần văn bản giống decorator bị bỏ qua.
