Won't work for me ...
In Test:
bool saveCalled = true; bool addCalledAfterSave = false; folderMock.SetupIgnoreArgs(f => f.set_AttributeValue(null, null)) .Callback(() => addCalledAfterSave = saveCalled);
set_AttributeValue (has 4 overloads) is called 3 times yet SetupIgnoreArgs won't get called ( addCalledAfterSave remaining false... )
I was inspired by your gist and created this variation.

Sure, do whatever you want with it. See https://gist.github.com/7Pass/1c6b329e85ca29071f42#gistcomment-2600736 which seems to be a better version though.

Just curious, what is the point of the
node.Value != null
check on line 53? If you have a method signature likefoobar(string, int, string)
and calledSetupIgnoreArgs(x => x.foobar(null, 0, null))
theint
will not be ignored.
