About the bug

On Chrome v101 and earlier versions, requestAnimationFrame works on both devtools_page.html and the panel.html (loaded via chrome.devtools.panels.create).

Since v102, it stops working on devtools_page.html. If you click "requestAnimationFrame from devtools_page" button, nothing will happen.
