Setting doImmediateRespawn to false does not work immediately

Steps to reproduce:

1. Create/open a world with cheats enabled

2. Run /gamerule doimmediaterespawn true

3. Die

4. Run /gamerule doimmediaterespawn false

5. Die twice

Observed result:
The death screen does not show up for the first 2 deaths and shows up for the last death.

Expected result:
The death screen does not show up only for the first death.
