`EXTRA_ARGS` not taking effect

I'm using docker compose and can't seem to get EXTRA_ARGS to take effect, for example:

version: "3"

services:
  redis:
    image: redis:7
    environment:
      EXTRA_ARGS: --loglevel warning

produces a startup log like

redis-1  | 1:C 05 Dec 2022 11:16:28.739 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
redis-1  | 1:C 05 Dec 2022 11:16:28.739 # Redis version=7.0.5, bits=64, commit=00000000, modified=0, pid=1, just started
redis-1  | 1:C 05 Dec 2022 11:16:28.739 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

redis-1  | 1:M 05 Dec 2022 11:16:28.741 * Ready to accept connections

If I put the argument into command, it works as expected:

version: "3"

services:
  redis:
    image: redis:7
    command: --loglevel warning

The startup log with that is reduced as expected:

redis-1  | 1:C 05 Dec 2022 11:16:41.963 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
redis-1  | 1:C 05 Dec 2022 11:16:41.963 # Redis version=7.0.5, bits=64, commit=00000000, modified=0, pid=1, just started
redis-1  | 1:C 05 Dec 2022 11:16:41.963 # Configuration loaded
redis-1  | 1:M 05 Dec 2022 11:16:41.964 # Server initialized

Is it a bug or am I just using EXTRA_ARGS incorrectly? I couldn't find any documentation about it in this repo.
