Chrome couldn't update a favicon.
ex) <link rel="shortcut icon" ...
It seems that link tag wasn't remove.
Because removeFaviconTag method compare "icon".
removeFaviconTag method compare
links[i].getAttribute('rel') === 'icon'
But getFaviconTag method compare string as regex.
getFaviconTag method compare
(links[i].getAttribute('rel') || '').match(/\bicon\b/)
Doesn't work contains another icon string in link rel on Chrome.
Thanks! This fix makes a lot of sense, i'll get this merged in,
Please release this update, it's important
