Resource Pack Models do not scale properly above 3.0.

Resource pack models no longer scale properly above 3.0 for the display head attribute.

For example if a model has the json below

"display": {
	"head": {
		"rotation": [0, 0, -136.75],
		"translation": [-3.25, -11.5, 5],
		"scale": [3.3, 3.2, 3.1]
	},
}

"display": {
	"head": {
		"rotation": [0, 0, -136.75],
		"translation": [-3.25, -11.5, 5],
		"scale": [3.3, 3.2, 3.1]
	},
}

It will look small or deformed on 1.21.11 while on 1.21.1 it will look as expected. I suspect that the scale is mistakenly being ignored at around 3.0.
