SetEmitterAngle does not work on Particle Emitter

Description

SetEmitterAngle has various incorrect effects/no effect on the emitter. The only one that seems to work correctly is if the angle was originally defined as a number and then setEmitterAngle is given a number. Any other combination seems to have unpredictable effects.

Example Test Code

class Example extends Phaser.Scene
{
    preload ()
    {
        this.load.atlas('flares', 'assets/particles/flares.png', 'assets/particles/flares.json');
    }

    create ()
    {
        const emitter = this.add.particles(400, 100, 'flares', {
            frame: [ 'red', 'green', 'blue' ],
            speed: 300,
            angle:0,
            // angle:[50, 80],
            // angle: { min:50, max:80},
            lifespan: 4000,
            scale: 0.4,
            blendMode: 'ADD'
        });

        this.input.on('pointerdown', pointer => {

            // emitter.setEmitterAngle(50)
            emitter.setEmitterAngle([150, 80])
            // emitter.setEmitterAngle({min:50, max:80})

        });

    }
}

const config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    backgroundColor: '#000',
    parent: 'phaser-example',
    scene: Example
};

const game = new Phaser.Game(config);

The only one that seems to work correctly is if the angle was originally defined as a number and then setEmitterAngle is given a number.

I think this is true of all the EmitterOps since v3.60. A workaround is

emitter.ops.angle.loadConfig({ angle: { min: 50, max: 80 } });

This is correct, it's not possible to change the EmitterOp type post-creation without reloading the config. If you start it with a number, you can change it to another number, but not an array, for example. If you need to dynamically change it, use a callback op type in the initial config.
