Sticky action buttons from a dropdown button set can't be clicked

I am looking into it

I am not able to progress more with this issue so unassigning myself.
Attaching some gif related to this issue in IS for better visibility.

I have the same issue with Feeds module 🐛 When using Navigation module, Save button doesn't trigger Active which display dropbutton actions when editing a feed content. In this case, dropbuttons are displayed, but not actions on click.
