@amireh amireh commented Nov 18, 2020

the workaround for handlebars-lang/handlebars.js/issues/748 employed a sorting
routine that was not commutative; its output relied on the order of its
arguments, and with the V8 engine upgrade in node11, that order has
changed1

the order of the arguments to Array#sory is considered an implementation
detail that we can't rely on

this patch reimplements that sorting routine to always return the same
result regardless of the order of its operands, and so it should work on
node <= 10 and >= 11

test plan: there is already a case for this, so I just added node12 to
the travis language matrix

flag = none

this pulls in a version of the package that can work under node > 10,
see instructure/i18nliner-handlebars#2

:: test plan

you need to try this in both node 10 and node 12, run webpack when you
switch versions

create a module in a course that has some students and add some stuff
to it, then view its progress and verify the student names show up
fine
