autoplay-policy arg not recognized in CICD

I am overriding the plugin fixture to allow for browser audio like so:

@pytest.fixture(scope="session")
def browser_type_launch_args(browser_type_launch_args):
    """Ensure the autoplay capapbility in the browser"""
    launch_options = {**browser_type_launch_args, "args": ["--autoplay-policy=no-user-gesture-required"]}
    return launch_options

This works perfectly fine when ran locally, but fails inside docker for ALL webkit tests with:

[pid=2503][err] Cannot parse arguments: Unknown option --autoplay-policy=no-user-gesture-required

What am I doing wrong?
