Unfortunately, I can't find anything in the current Comp Rules to support my answer, but I'll give it anyway...
I would think any Hero you choose would be considered 'inactive' while under the Spirit Jar. That Hero should not be able to be interacted with by any player until 'freed' from the Spirit Jar.
Hopefully, Dan or somebody can confirm this. (..or maybe an updated Comp Rules that explains how Heroes behave while under Feature Objects...
