There is something wrong with the product tabs. Previously, when a tab is clicked, the page remains stationary and just loads the content for the respective tabs. Now, when a tab is clicked, the page goes back to the top of the page. This is not right.
Strange, but it shouldn’t work this way. Maybe you have some plugin or custom JS script that changes this functionality. Try to disable external plugins and be sure that you don’t have any custom JS code.
