**Description** The roosterjs-editor-api provides a [`toggleCodeBlock`](https://microsoft.github.io/roosterjs/docs/modules/roosterjs_editor_api.html#togglecodeblock), but there is no corresponding `isCodeBlock` in [`FormatState`](https://microsoft.github.io/roosterjs/docs/interfaces/roosterjs_editor_types.formatstate.html). **Expected behavior** I expect there to be an `isCodeBlock` just like there is a [`isBlockQuote`](https://microsoft.github.io/roosterjs/docs/interfaces/roosterjs_editor_types.formatstate.html#isblockquote) for [`toggleBlockQuote`](https://microsoft.github.io/roosterjs/docs/modules/roosterjs_editor_api.html#toggleblockquote).
