Repro:
1. Pick Morphling and get Aghanim's Scepter
2. Create an allied hero from the list below and level up the named spell
3. Create a Hybrid illusion of the allied hero
4. Right before the Hybrid expires, cast the named spell
(in case of bouncing spells, create multiple targets which are all within bounce range)

Result: The named spell immediately ends on death.

Expected: Just like how it is for the original hero, the spells should not end upon the death of the caster.

Affected spells:
1. Zeus' Arc Lightning
2. Rubick's Fade Bolt
3. Leshrac's Lightning Storm
4. Leshrac's Diabolic Edict
5. Sand King's Epicenter
6. Batrider's Firefly fire trail
7. Enchantress' Nature's Attendants
