Hi, Cindy
Thanks for contacting us.
On all browser, scrollbar will automatically elastic depending on the content on browser. When the content is long, the scrollbar will automatically shorten and vice versa, when the content is shoren, the scrollbar will automatically longer or disappear.
JUX Social stream will work as same as that rule. When you click on the tab, the social icon will display different on scrollbar. Therefore, the scrollbar will auto adjust to display the content.
Even though this will make you feel annoying, however you can not disable scrollbar if you want to display full content on your website.
