Created attachment 465468 [details] Video comparing chrome and webkit (via playwright) During testing with Storybook, we use playwright to navigate to a browser (chromium, firefox, and webkit) containing just a single iframe with the component in question. Expected: When I tab to navigate through the focusable elements on the page, I expect tab to loop endlessly through all focusable elements on the page (including the URL bar, etc). Actual: When there is just a single component/iframe on the page, the tab focuses only focusable elements within that component. Tab can no longer remove focus from the component and can cannot focus other page elements like the URL bar. This behavior is only seen on webkit 16.4, chromium and firefox do not have this issue.
