steps() uses deltaEMethod inconsistently

The steps() function makes four calls to deltaE(), but only one of them passes the deltaEMethod option.

Line 86 in ffa9c3f

let totalDelta = deltaE(c1, c2);

Line 112 in ffa9c3f

let ΔΕ = deltaE(cur.color, ret[i - 1].color, deltaEMethod);

Line 127 in ffa9c3f

    
           maxDelta = Math.max(maxDelta, deltaE(color, prev.color), deltaE(color, cur.color));

I noticed this after calling

steps(
	{ space: sRGB, coords: from },
	{ space: sRGB, coords: to },
	{ space, steps, outputSpace: sRGB, hue, deltaEMethod: 'OK' },
)

without having the Lab color space registered first.

Is this behavior intended?
