- [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)

### ⭐ Suggestion

Typescript should now support the FocusVisible property of FocusOptions.

### 📃 Motivating Example

The FocusVisible FocusOption is now supported on all major browsers except Samsung Internet. It is supported on all desktop browsers. It was stated under [the previous issue on the topic](https://github.com/microsoft/TypeScript/issues/61458) that a new issue should be opened when the feature is more widely supported, and it is now more widely supported.

### 💻 Use Cases

1. What do you want to use this for? Ensuring the focused element is visibly focused.
2. What shortcomings exist with current approaches? There isn't a workaround for this.
3. What workarounds are you using in the meantime? There isn't a workaround for this.

まず、TypeScript の DOM 型定義にある HTMLElement.focus() と FocusOptions の宣言を見つけます。既存の focus オプションがどのように表現されているかを確認し、適切な宣言に FocusVisible プロパティを追加します。HTMLElement.focus() の呼び出し時に TypeScript が FocusVisible を受け入れれば完了です。
