HTML content attributes and dom properties are different things.
Like the majority of cases, DOM properties make sense here. The async
property is specified in HTML5, which copied the property from IE.
W3c specs use the term "attribute" to mean "dom property". DOM
properties are not HTML content attributes.

getAttribute/setAttribute is not any more correct than DOM properties
but it is less interoperable.
Some content attributes "reflect" object state, others do not. Which
attributes "reflect" varies between browsers and the attribute in
Setting an attribute to the empty string may have the effect of
removing the attribute in some browsers.
