nit... is it worth combining these into a single if (key.IsEmpty() || val.IsEmpty()) return just to make things a bit more compact?

We usually fail fast when a JavaScript exception is pending to avoid unsafe calls into JavaScript in that state. It seems that ColumnToValue() does not call into JavaScript, but unless someone feels strongly, I'd err on the side of caution here.
