Okay.  There's one more issue to resolve.  An asynchronous preview will
return t but no preview is placed yet.  If the preview then fails when
the callback runs, we will have an overlay without a preview that hasn't
been cleaned up.  How do you suggest handling this case?

The only thing I can think of is that the async preview-func should call
org-link-preview-clear on the failed preview by itself, and we should
include this expectation in the org-link-parameters documentation.
