研究方向

First, locate the `dom.isFocusable` function in the axe core source code, likely in `lib/dom/is focusable.js`. Read the current implementation to understand how focusability is determined. Then, consult the HTML specification to determine when `audio` and `video` elements (with controls attribute) are focusable. Modify the function to include these cases. Check existing tests in `test/dom/is focusable.js` and add test cases for `audio` and `video` elements with and without controls.
