Steps to reproduce:
* Install `fonts-noto-color-emoji-0~20180424-2`
* Open PureBrowser 52.8.0
* Visit https://getemoji.com
* See also https://en.wikipedia.org/wiki/List_of_Emojis
What should happen:
* All emoji render in colour
What happens instead:
* some emoji render in color as expected
* some emoji render in black and white (rather than color)
* some emoji render in color, but are far too big

Notes:
* Related link: https://unix.stackexchange.com/questions/444141
* This persists after running `fc-cache -f -v`
* The CSS on that page specifies the "Segoe UI" font-family, if I remove that, the problem persists (in fact, more emoji appear in black and white) -- see below
* Another page that doesn't need CSS hacking: https://en.wikipedia.org/wiki/List_of_Emojis (large emoji appear at the bottom of the page)
