Uh oh! @dylanatsmith, the image you shared is missing helpful alt text. Check your issue body.

Alt text is an invisible description that helps screen readers describe images to blind or low-vision users. If you are using markdown to display images, add your alt text inside the brackets of the markdown image.

Learn more about alt text at Basic writing and formatting syntax: images on GitHub Docs.

Just passing by: overflow: scroll should be on the ActionList inside the Overlay. not on the overflow itself, that way we can ensure the border radius of the Overlay stays intact

Wondering if someone in Primer Design might be able to take a look and weigh in on the CSS change needed here?

@camertron can you follow up on this if it's React?

@tallys confirmed via Storybook that I believe this is happening in React.
