Yes it is nasty.  We could theoretically work around the bug with
customized serialization logic in Element, but it'd take a lot of ugly
code.  Would have to make the content List transient and walk through it
piece by piece writing out each "node", and if the node was a string >
64K then it'd have to be broken into sub strings with those serialized. 
On read in you'd have to do the opposite.  Would also need some way to
represent what kind of List was serialized, so you could construct a new
list of the same type.

That's the right way to fix it.  :-)
