4039	Bug with _GUICtrlTreeView_Delete	Kanashius	Jpm	"The _GUICtrlTreeView_Delete deletes random controls instead of the provided item using x64 AutoIt.

The issue already came up and was fixed, if a ControlID was provided, but it was overlooked to fix it for ControlHandles, too.

Comment in the UDF to that:
{{{
; Danyfirex founding
; If We Use IsHWnd It will always return false. So You will always call _GUICtrlTreeView_GetItemHandle and You will get the GUICtrlGetHandle issue that happens randomly
; So let's use IsPtr and remove GUICtrlDelete So we can always delete using the Control Handle.
}}}

As it already came up as a Bug, I did not write an additional Example for that.

Proposed fix to change
