I'd like to support this. I typically have an array of pointers to table bodies, and I want to search those looking for a particular row by id. Only one of the table bodies is in the DOM at any given time, and at present for a table body that is not in the DOM I have to hook it to a fragment and then do something like:

   rowPtr = fragPtr.querySelector ("#" + id);

I'd rather be able to use getElementById.
