How do I change `customize` dynamically, and why doesn't the component update with ticks?

How do I change the fill and stroke during the lifecycle?

• agree only works when not touching the display property and using svg mode.
• agree2 doesn't work, with or without svg mode.

<script setup lang="ts">
const agree  = ref(false)
const agree2 = ref(false)

const setChecked   = (content: string) =>
  content
    .replaceAll(/stroke="[^"]*"/g, 'stroke="black"')
    .replaceAll(/fill="[^"]*"/g, 'fill="white"')
const setUnchecked = (content: string) =>
  content
    .replaceAll(/stroke="[^"]*"/g, 'stroke="black"')
    .replaceAll(/fill="[^"]*"/g, 'fill="yellow"')

const customize = (a, b) => (content: string) =>
  content.replaceAll(/stroke="[^"]*"/g, `stroke="${a}"`).replaceAll(/fill="[^"]*"/g, `fill="${b}"`)
</script>
<template>
  <label>
    <input
      v-model="agree"
      required

      class="invisible absolute -z-10"

      name="local:checkbox"
      :class="{ hidden: !agree }"
    />
    <Icon
      :class="{ hidden: agree }"
      mode="svg"
      :customize="setUnchecked"
      name="local:checkbox"
    />
    Yes

  <label>
    <input

    <Icon
      :class="{ hidden: agree }"

<svg width="20" height="20" viewBox="0 0 20 20" fill="none">
  <rect x="0.5" y="0.5" width="19" height="19" rx="3.5" fill="#24A3B6"/>
  <rect x="0.5" y="0.5" width="19" height="19" rx="3.5" stroke="#24A3B6"/>
  <g clip-path="url(#clip0_4188_74097)">
    <path d="M6 9.5L9.125 12.625L15.375 6.375" stroke="white" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"/>
    </g>
  <defs>
    <clipPath id="clip0_4188_74097">
      <rect width="15" height="15" fill="white" transform="translate(3 2)"/>
      </clipPath>
    </defs>
  </svg>

// app.config.ts
export default defineAppConfig({
  icon: {
    size             : '20px',
    customCollections: [
      {
        prefix: 'local',
        dir   : './assets/images/icons/'
      }
    ],
})

The number of times I've restarted Nuxt for debugging this is horrendous.

Reproduce the two checkbox examples using the component and the local collection configured in app.config.ts, comparing svg and non-svg modes. Trace how customize, display, and reactive updates are handled, then verify that fill and stroke changes are reflected during the component lifecycle for both examples.
