 where emoticons are broken. Is is running Debian testing. That said I
 realized that it can be a bit hard to see this if one is upgrading from
 5.0.7 as it seems to work then but after shutting the browser down and
 restarting it no emoticons are shown.  (This reminded me at one of the
 failure modes of our start script. :/)

 > I think we can start with this font as a fix for this bug. Two things
 regarding the patch:
 > 1) You don't use `NOTOEMOJIFONT_VER` anywhere, so we don't need it.
 Which reminds me that the same seems to hold for `NOTOCJKFONT_VER`.
 > 2) Please remove the superflous newline below `+- "NotoEmoji-

 Here's a patch with these things fixed:
