Thanks, Glen!
This makes sense. I wonder if this should be a bug in the bootstrap

I am trying to find a way to add dynamically the content, for example
pointing the describedBy to an empty div that I can populate when the
content is needed.
Or using a different set of aria-attributes, like aria-haspopup
