Looks good, just a small suggestion.
Thank you!

| Note that this property applies only to {{Glossary("Scroll_container", "scroll containers")}}. In particular, since an [`<iframe>`](/en-US/docs/Web/HTML/Reference/Elements/iframe) is not a scroll container, setting this property on an iframe has no effect. To control scroll chaining from an iframe, set `overscroll-behavior` on both the [`<html>`](/en-US/docs/Web/HTML/Reference/Elements/html) and the [`<body>`](/en-US/docs/Web/HTML/Reference/Elements/body) elements of the iframe's document. | ||

| A {{Glossary("Scroll_container", "scroll container")}} that has no scrollable overflow (for example, when `overflow: hidden` is set and the content doesn't extend beyond the container) is always considered to be at its {{Glossary("Scroll_boundary", "scroll boundary")}}. So setting a non-default `overscroll-behavior` such as `contain` or `none` on it will prevent scroll chaining to ancestor scroll containers. This can be used to prevent background scrolling while a dialog or overlay is open. |

Just a tiny suggestion to shorten the first sentence. The parenthetical content could be "(for example, an element with overflow: hidden)".
Or even changing it to the style used in the release note will work: ", such as an element with overflow: hidden,"
