Bug description

When using the latest version of react-big-calendar, the prop dragFromOutsideItem seems to be expected even if it’s not defined.
If I don’t provide it, I get the following error:
TypeError: _this.context.draggable.dragFromOutsideItem is not a function

Expected Behavior

if dragFromOutsideItem is not defined, the calendar should handle it gracefully instead of throwing an exception.

Actual Behavior

When dragFromOutsideItem is not defined, after dropping an event, an error is thrown

react-big-calendar version

1.19.4

React version

19.0.0
