It sounds like you're experiencing an issue with the table drag element's positioning within the Claro administration theme on Drupal, specifically when using Chromium browsers. This can be particularly problematic for user experience, especially when dealing with large draggable elements.
One possible workaround to consider, until a permanent fix is implemented, could involve custom CSS or JavaScript adjustments to alter the drag handle's positioning or enhance its visibility and accessibility. For instance, you might use CSS to adjust the drag handle's position to the top of the draggable item, ensuring it's consistently accessible regardless of the item's size or the browser in use.
Additionally, exploring JavaScript solutions that dynamically adjust the drag handle's position based on the user's interaction or the viewport size could offer a more responsive and user-friendly approach. This could involve listening for drag events and altering the handle's position to ensure it remains within an easily reachable area of the viewport.
It's also worth checking if there are any open issues or patches submitted by the community addressing this problem. Contributing to such discussions or patches can not only help you find a temporary solution but also assist in speeding up the resolution of the issue for everyone involved.
Remember, when customizing or extending functionality, it's essential to thoroughly test your changes across different browsers and devices to ensure compatibility and maintain a consistent user experience.
