Illagers in raids continuously try and fail to pick up ominous banners if they can't reach them

Pretty much a bug that's never been noticed by many.

Simply drop an ominous banner in a two block tall tower while a raid is ongoing, a few illagers will try to retrieve the banner, and will just stay there until one of them is a captain.

I'd cosider this a bug because this can easily distract illagers and can let players win a raid easily

To reproduce

1. Cause a raid

2. Only kill the raid captain and take the ominous banner

3. Have a two block tall tower and drop the banner there
   → ❌ The remaining illagers will rush towards the banner while they are unable to grab it

4. Go to survival
   → ❌ They'll try to attack the nearby player while trying to retrieve the banner
