Damage command ignores player invulnerability frames

when putting a /damage command block on repeat, players continuously take damage each tick rather than only when the invulnerability timer is exhausted.

UPDATE: I have discovered that this bug is in relation to bug MCPE-167651.

This bug does not occur without a damage multiplier reduction behavior set. A more in-depth explanation is available in the above link, consider the rest of this report as inaccurate.

Steps to Reproduce:

1. give yourself Resistance 5.

2. Set a command block to damage yourself (i.e.: /damage @p 1 entity_explosion)

3. Go in survival mode.

Results:

You take damage at every tick.

Expected Results:

You take damage only when you're not in your hurt-invulnerable state, meaning taking damage roughly every half-second.
