Do not despair! I overanalyze things too!

The spell ends when the caster (loses their magic or) dies. That is unless it's a stand alone spell. The series never talks about any details of magic when it comes to finer magic system fules, but I assume that whatever spell is maintained by the caster ends when  they die, while the enlosed spells continue on.

Zelena was faking the ice effects after Ingrid died and Elsa put up the Ice wall, Ingrid just kept regenerating it.

Zelena could have, but Ingrid probably put up the containment spell, for her to separate herself from Rumple in her own Storybrooke bubble.
