Bug 218339

Created attachment 412647 [details] Minimal sample html page to reproduce the bug. ### Overview The HTML Content Template element `<template>` does not respect the HTML5 input type="color". Instead of rendering a color picker, an ordinary input field is shown. ### Steps to Reproduce Open the attached html file in a Safari browser. ### Actual Results An input text field is rendered. ### Expected Results A color picker should be rendered. ### Additional Builds and Platforms Doesn't occur on current version of Chrome and Firefox. ### Additional Information Above, we reproduced the bug using a template tag as part of the markup of a html document. The bug also occurs, when create a template element dynamically using javascript: const template = document.createElement('template') template.innerHTML = '<input type="color">' const fragment = template.content document.body.appendChild(fragment.cloneNode(true)) The bug does not occur when rendering to a div. The following code can be used as a **workaround** for the bug: const div = document.createElement('div') div.innerHTML = '<input type="color">' const fragment = document.createDocumentFragment() fragment.append(...div.childNodes) document.body.appendChild(fragment.cloneNode(true)) Here you can find a benchmark that compares the workaround with the canonical solution: https://esbench.com/bench/5f9ac111b4632100a7dcd4e0 Thanks!
