Sounds like a classic IE quirk with event handling. It’s likely the click event for removing the overflow class isn’t firing properly after the scroll action. You might need to explicitly remove the class before triggering the scroll, or add a fallback for IE using setTimeout to ensure the class gets removed. IE often handles event order differently, so a small workaround like that usually fixes it.
