Incorrect lighting on translated object

A lighting bug was introduced recently. Models that used to render correctly started showing "double lighting" across parallel surfaces.

Expected Behavior

Consistent global lighting as shown here in @jscad/web@2.4.3 and before:

Actual Behavior

A double reflection of the light source on the translated cylinder on @jscad/web@2.4.4 and after:

Steps to Reproduce the Problem

const jscad = require("@jscad/modeling")
const { cylinder } = jscad.primitives
const { rotateY, translate } = jscad.transforms

function main() {
  const radius = 20
  const height = 80
  const segments = 80
  return [
    rotateY(Math.PI / 2, cylinder({radius, height, segments})),
    rotateY(Math.PI / 2, cylinder({radius, height, segments, center: [0, 0, 82]})), // good lighting
    translate([-82, 0, 0], rotateY(Math.PI / 2, cylinder({radius, height, segments}))), // bad lighting
  ]
}

module.exports = { main }

The problem only appears on the translated cylinder, not the re-centered cylinder. Also worth noting that these are all independently constructed objects, so this does not appear to be a caching, or copying bug.

Specifications

• Version: @jscad/web 2.4.4...2.5.3 (current)
• Platform: web
• Environment: browser

Start by running the JavaScript reproduction in the issue with @jscad/modeling and compare the translated cylinder with the re-centered cylinder in the browser. Trace the rendering path responsible for lighting and verify that translated objects show consistent global lighting like @jscad/web 2.4.3 and earlier.
