Create style elements and modify their text content instead of using innerHTML to create the whole `<style>` element with its content. That way style insertion done at bootstrap time doesn't interfere with Trusted Types restrictions in Chrome (https://bit.ly/trusted-types). Remove the type attribute - `text/css` is default: https://html.spec.whatwg.org/#update-a-style-block. Closes #17014
