Oh!  I see!  The first time I get the message, `max-specpdl-size' is
1300.  Then each time I get it, it increases by 200, until it's finally
large enough at 2100 to descend that deep.

Is this by sneaky design?

Anyway, I still have no real idea as to how to handle this.  Do a
stack-based "depth" investigation first to see how deep the DOM is, and
then refuse to render it if it's too deep?
