Wolf is rendered too dark when not directly affected by skylight

Seems that the average between skylight and block light is not calculated well for wolfes.

Seems to me that instead of taking the max( skylight, Blocklight) an weighted (60/40) average is used.

I think these wolves are affected by a bug which makes them stay wet forever and never shake the water off. This combines with MC-105248 (wet wolves are too dark) to cause this bug.

That happens to me, but the wolf permanently stays dark until I reload the game.

I think this bug should be re-opened. I'm on a multiplayer server and it actually happens even when the wolf does have direct access to sunlight, sometimes. I'm in 1.16.5.
