Clear button on DropDownTree doesn't reset MVVM-bound value

When using the MVVM value binding with the DropDownTree, pressing the X button to clear the selection does not clear the bound field in the viewmodel. If the DropDownTree is configured with valuePrimitive=true, then the VM bound field is completely unchanged If the DropDownTree is configured with valuePrimitive=false, then the VM bound field is set to the string value of the prior selection's ID.

So my present workaround is to use valuePrimitive=false and if the VM bound field ends up being a string instead of an object, then treat it as null instead. This adds a bunch of extra and ugly code to my app - is there any way to get the widget to simply set the bound VM field to null when the user clicks the X?
