The warden indefinitely roars when attacked by multiple entities

Can confirm, sometimes they'll even stop mid-attack before their initial target is dead just to roar at another mob, leading them to take way more damage than necessary. I wonder if this works with players, too..

Unfortunately this seems to not be completely fixed. The Warden is better at it, but with slightly more mobs than what was previously shown, the Warden will eventually keep roaring over and over again while continually being attacked, still taking a lot of damage and sometimes even dying (it lost this fight for example)

Still in 22w15a

As previously noted, this still happens, it just requires a slightly greater number of mobs before the "fix." In 22w14a. I think this is because it prioritizes roaring over counterattacking.

Although this video was intended for a different bug report, I'll post it here too as it also demonstrates how Wardens still roar in the middle of being attacked by many mobs

I can confirm that this problem has not been fixed

In 22w19a, it seems they try to keep roaring at mobs but now stop midway to attack things. So functionally this is fixed though visually they do try to roar

It roars but it lets itself be interrupted to melee something.
