How to contain dragging of webamp to a specific div?

Hello,

Trying to contain dragging of #webamp to a specific div on my website, but can't figure it out.
The div in question is not its direct parent if that helps.

Ideas?

No file, test, or entry point is named. Start by locating the #webamp dragging implementation and its public configuration, then determine whether dragging can be constrained to a non-parent div. Done means a documented and tested way to apply that constraint, or a clear explanation of the supported limitation.
