 Windows 8 seems to be affected as well.

 these fonts.

 from the whitelist. This makes the Emoji fonts identical on all versions
 of Windows. The Noto Emojis don't look the quite the same as the native
 Windows fonts.

 Hm, this is pretty unfortunate especially as we probably want to test
 whether the bundling mechanism is working on Windows as well properly.
 But, yes, I think we could try that route. I am not really inclined to
 wait for that for 5.5.1, though, as #18169 and #18168 are more important
 and I would like to see some testing with this approach.
