Throws an exception after using Tab to perform completion

Under Win11, after the EditControl completion box pops up, select the custom completion member, and the control throws an exception after pressing Tab.

Exception information: System.NullReferenceException: "Object reference not set to an instance of an object."


Exception document:EditControl.cs

Exception code:

Line 2565: intellisenseArgs.SelectedItem = intellisenseBox.SelectedItem as IIntellisenseItem;

The intellisenseArgs here is empty, and there is an exception when referencing its own field.


Suspected root cause: An error was reported in the EditControl source code after using Tab to select and complete members in the empty line
