The attribute is not added.  The controls are simply displayed, which happens
to be the same thing that occurs if you set the attribute.

Disabling the control UI when there is no possibility of providing custom
controls is almost certainly going to be done accidentally, by an author
assuming that scripting is always on and their script-based controls will be
added, and so just omitting the @controls attribute.
