When under both poison and wither, the poison heart texture is used
Wither is meant to deal damage and make hearts harder to see, and this behaviour makes poison able to nullify half of that seemingly unintentionally.

MC-205102.Even though i don't see it as bug, i can confirm that it exists in 1.17 pre 2
Can confirm in 1.17-pre3
Can confirm, and it works with freezing too.
But unless you expect them to make different heart textures for each combination of poison, wither, and freezing, I don't think they would be able to do that.
Alternatively, a more realistic solution, make it cycle between the different heart states if you have multiple heart effects.
Can confirm in 1.17.
