Emit on direction changing

[lefhl]

Hello! Is there a way to get information about positioning of popper content from component? I have custom select with straight corners on the generic side of content and trigger element and rounded ones on the opposite side. There is a problem when positioning changes from bottom to top with styling of the elements. That's customizable for content thanks to [data-popper-placement="top"], but there is no way for the same thing for trigger element.
