Greetings from Syncfusion support.
We have checked your attached chrome and Firefox video. We suspect the cause of closing of sidebar is due to the gestures in the Sidebar component. By default, when we click drag on the Sidebar will trigger close event of the sidebar. This functionality can be disabled in the Sidebar by setting enableGestures property as false.
