This makes a lot more sense as a solution than your previous patch. This part is
the only part I find surprising... Do we really not reset DataRefs elsewhere?
Ideally, we'd just use access() and copy in a default StyleMultiColData (which
could potentially avoid some RefPtr churn). Seems like a lot of yak shaving,
though. WDYT?

this patch is worth, though.
