Element modal form menu opens beyond map dedicated whitespace, overlaps with browser scrollbar

Steps reproduce:

1. Have some elements on the map
2. Click on the element for modal form menu to appear
3. try to close it.

Video attached (FireFox):

Actual result:

(Chrome)

Modal form menu goes under browser scrollbar. Close icon is obscured

Expected result:

There is whitespace dedicated to maps

Would be nice for modal form menu elements to open within those borders. This will prevent elements from overlapping with browser control elements
