A non-disabled, rendered component should have a submittedValue. By
hacking the client DOM you are kind of invalidating to contract of the
component.
I think a better method is to use PPR to change the disabled property
of the component & re-render the component. Renderers are not supposed
to have to handle external changes to the DOM they encode.
