Calling setUserScale inside setResizeCallback results in an infinite loop

[LandonSchropp]

Phaser version(s): 2.7.7
Live example: https://codepen.io/LandonSchropp/pen/vmeZXr

What Should Happen

The documentation for Phaser.ScaleManager.USER_SCALE states:

The game Display is scaled according to the user-specified scale set by setUserScale. This scale can be adjusted in the resize callback for flexible custom-sizing needs.

I'd like to do some custom resizing, and setResizeCallback seems to be the say to do it. So I added this to my create function:

game.scale.scaleMode = Phaser.ScaleManager.USER_SCALE;
      
game.scale.setResizeCallback(() => {
  console.log("RESIZING!");
  game.scale.setUserScale(1.5, 1.5, 0, 0);
});

I would expect this to get called when the viewport is resized, adjust the to 1.5 times the default size and then be done.

What Actually Happens

The resize callback gets caught in an infinite loop. Calling game.scale.setUserScale(...) triggers the resize callback, which calls setUserScale again, and so on.

Other Notes

You guys are awesome! Thanks for taking a look.

This seems to be how it's intended to work, but it's very strange. It does the same thing at least back to v2.4.4.

I'm getting this wrong behavior

@samme but in the docs says: This is the appropriate place to call setUserScale if needing custom dynamic scaling.
