https://newdocs.phaser.io/docs/3.55.1/Phaser.GameObjects.Sprite#chain
https://newdocs.phaser.io/docs/3.55.2/Phaser.Animations.AnimationState#nextAnim
Chaining an animation set anims.nextAnim, if null, to the animation to chain, but after running sprite.play(...) the value turn to undefined, thus the animation to chain goes to anims.nextAnimsQueue leaving anims.nextAnim to undefined forever.
Example Test Code
console.log(sprite.anims.nextAnim) // null
sprite.chain(key)
console.log(sprite.anims.nextAnim) // given key
sprite.play(key)
console.log(sprite.anims.nextAnim) // undefined, it's a bug ?full running code: (run on https://labs.phaser.io/edit.html)
