Describe the bug
After updating RM from version 4.6.0 to 4.7.0, dropdowns exhibit unexpected behavior:
When multiple dropdowns are present, opening one does not close the previously opened dropdown.
Once this occurs, the open dropdown cannot be closed manually by clicking elsewhere on the page.

To Reproduce
Go to a page with two or more dropdown components.
https://react-magma.cengage.com/version/4.7.0/api/dropdown/
Open one dropdown.
Open another dropdown without closing the first one.
Attempt to close the open dropdown by clicking outside of it.

Expected behavior
Opening one dropdown should automatically close any previously opened dropdowns.
Clicking outside of an open dropdown should close it.
