Animation : duration per frame not working

[supertanuki]

Version

• Phaser Version: tested in 3.88.2, 4.0.0-rc.1
• Operating system: Any (Ubuntu...)
• Browser: Any (Firefox, Chrome..)

Description

In the doc https://docs.phaser.io/phaser/concepts/animations#add-animation we can specify a duration per frame :

this.anims.create({
  key: "spikes",
  repeat: -1,
  defaultTextureKey: "spikes",
  duration: 3300,
  frames: [
    { frame: 0, duration: 3000 },
    { frame: 1, duration: 100 },
    { frame: 2, duration: 200 },
    ...
  ],
});

This does not work. In the game, all frames have the same duration.

Nota : not fixed by the commit mentioned here #7070 (tested on 4.0.0-rc.1)

I have tested this on 4.0.0-rc.2 and it appears to be working as expected.
