Striders and blazes do not take five times the damage when using /damage with freeze type

The bug

Striders and blazes do not take five times the damage when using /damage with freeze type.
As they stand in the snow, they take five times more damage than other mobs, but using the /damage with freeze type is not.

Reproduce steps

1. Summon a strider or blaze.
2. Use the /damage command:
   Strider

   /damage @e[type=minecraft:strider,limit=1] 1 minecraft:freeze at 86 65 1

   Blaze

   /damage @e[type=minecraft:blaze,limit=1] 1 minecraft:freeze at 86 65 1

3. Use the command four times.
4. Found that the target mob was not killed(The health points of both striders and blazes happen to be 20).
5. Found that the damage was not multiplied by five.

Expected to happen...

• Strider or blaze do five times as much damage when they take weakness damage.
