When the "Universal Anger" game rule is set to true, aggression breaks on Spiders, Cave Spiders (both in daylight), and Endermen. When hit by a snowball or taking damage, they will not retaliate most of the time.
Piglins (tested while the player is and is not wearing Gold Armor), Zombified Piglins, Polar Bears, Wolves, Bees, and Iron Golems all work as intended.
Reproduce:
In a new or old world, set Universal Anger to true
Throw a snowball or damage a Spider/Cave Spider (in daylight), or Enderman
The monster will not attack back.
Other notes:
Looking at an Enderman still works normally, and the player will get attacked.
Attacking one of these 3 mobs with universal anger disabled works normally, and they mob continues to attack the player as they should when universal anger is enabled mid-combat, even when the player continues to attack with universal anger enabled.

I don't think it's intended, since Spiders and Endermen are supposed to fight back when attacked. Universal Anger, if anything, would just make these mobs attack any nearby player instead of ignoring them.
Devs are certainly welcome to disagree with my thoughts though 😅
Found another report that is effectively a duplicate of this, but doesn't include spiders in the report.
Since your issue was reported later, this is a duplicate of MC-195278.
I can confirm this issue, but it might intended.
