The sample scenario you provided might not be correct. I would argue 
that changes made to foo.style object should necessarily lead to the 
foo@style attribute value change, similarly to input.value property not 
leading to the change of input@value attribute etc. The attribute unless 
modified by the means of DOM methods (such as removeAttributeNode, 
setAttributeNS etc. that will actually lead to a dispatch of 
DOMAttrModified) should preserve its value observed from markup.
