The Reference Icon no longer produces popup on hover in Kingston
The behavior of the reference icon that displays next to a reference field on a form or at the beginning of each row in a list has changed with the Kingston release.
Starting with Kingston, the preview popup no longer displays when a user hovers over the icon. From Kingston forward, users are required to click on the icon in order to show the preview popup and then have the option to open the record from the popup view. This behavior is consistent across the platform anywhere this icon is used. This change was made to bring ServiceNow into compliance with accessibility requirements and to provide a more consistent user experience throughout the platform across devices.
