[Gameplay] - [Zilean] - Losing 50 hp briefly after being revived by Chronoshift.

Steps to reproduce:

1. Launch the application.
2. In the game settings, active the heal combat text.
3. For ease of reproduction, enter a practice tool game as Zilean.
4. Get to level 6 and level up the ultimate.
5. With the ultimate on, die.
6. Notice that 50 hp is lost about half a second after reviving.

Actual result: Upon reviving, the player is healed by the correct amount of hp shown in the ability description, about half a second later, around 50 hp is lost.

Expected result: The revived player does not lose any hp.

Additional information:

• The issue seems to occur more often the first time Zilean ults.
• The issue has only been tested in the practice tool while ulting on self because I currently have no friends connected and I'm lazy.
• Repro rate: 3/5
