[MC-190336] Deleting a turtle helmet you were wearing shortly after wearing it causes the water breathing effect to be stuck at 0

In a creative world, place down a repeating command block and then type "/item replace entity @p armor.head with minecraft:air"; then run it so that it continually repeats. (you might want to turn of commandBlockOutput)
Wear a turtle shell. The item will be deleted as expected, but the potion icon will flicker until it reaches 0. It will then be stuck at 0 until you relog or go to the nether.

Does this also happen in 1.15.2?

Yes, I just tested it. It works for 1.15.2

Can confirm in 20w46a.

Can confirm in 20w51a. Here's the updated command since the command provided in the description no longer works.

This seems to describe the same behavior as MC-239935, either relates, or duplicates.

Yup, it's a duplicate.
