 properly but `snowflake` barfed.

 I think that although we built it using gcc 8.3.0, by chance the browser
 did not use any of the functions added in the new libstdc++, so it was
 still compatible with the libstdc++ provided by Debian 9. However this
 changed with the switch to esr68 and this now prevents the browser from
 starting too (which should be fixed by #31646).
