Ech, ignore that commentary.  Diffing the full set of IDs isn't
really relevant here:  PPR can, of course, introduce new IDs.
It just can't introduce new *top* IDs - each fragment has to
point to an existing ID.  We've got two fragments in here:

<div id="acctPage:acctTable">
<span id="_acctForm_Postscript">

And these do seem to be in the page already.  But even
if they weren't, it seems that the current JS code would simply
drop them and move on.

Tim, could you by any chance use FireBug's JS debugger to
step through TrPage.prototype._handlePprResponse()?  It's
not clear where this JS error is coming from.

(FWIW, the basic table row-disclosure demo seems to be working
fine for me, at least on FF (haven't tested IE)).
