Sometimes a Twitter page uses "apple-touch icon" instead of "shortcut icon" (I notice it when reloading on the Media tab on a account).
Some small additions to headFound(head) fixes this:

const twitterIconBase64 = "data:image/x-icon;base64,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";
const shortcutIcon = head.querySelector('[rel="shortcut icon"]')
if(shortcutIcon !== null) {
shortcutIcon.href = twitterIconBase64;
}
const appleIcon = head.querySelector('[rel="apple-touch icon"]')
if(appleIcon !== null) {
appleIcon.href = twitterIconBase64;
}

Disregard this, I was wrong. It seems like appleIcon was not the problem and I just got unlucky in the way it worked when I tested it.
