tdf#128550 set sub item on the ancestor node.

The target of a animation node may resolved to
a subitem. However it only has effect on a
iterate container or animate node, not on any
other containers. Subitem setting like background
and paragraph got ignored, so everything were shown
together.  The patch find the ancestor node
that is iterate container or animate, and set
the subitem on it.
