Big Map Keybind Issue

When I change the keybind for the Big Map, the new key opens the map but does not close it.

For example, I changed the bind from “M” to Mouse Button 4 (side button). Pressing that button opens the Big Map correctly, but pressing it again does not close it. The only way to close the map is by pressing “Esc.”

This issue makes the keybind inconsistent and less functional compared to the default behavior, where M opens and closes the map correctly.
