Description
Existentials at the top of the RHS of rewrite rules are separated and the variables renamed (to avoid name clashes).
When such a rule is applied, the variables need to be renamed back in the result term, and the \exists re-added.

Research direction
Start by tracing the rewrite-rule application path that handles existentials separated from the top of the RHS. Follow how renamed variables are represented in the resulting term; done means the original variable names are restored and the existential quantifier is re-added when the rule is applied.
