Dropdown `data-boundary` option not working in scrollable column

Created by: jacobmllr95

When a dropdown is placed in a scrollable column (.col) the data-boundary option has no effect. As @rinick pointed out here this is due the columns position: relative; property.

Is this something Bootstrap or popper.js can/should fix or has the user to deal with it?
