1750955 - Add pref for array grouping in nightly

Status: RESOLVED FIXED

(Core :: JavaScript Engine, task, P1)

Description

[Yulia Startsev [:yulia]]

We have a webcompat regression on groupby. We should add a pref so that users can continue to use nightly unimpeded while we determine how broad the breakage is.

This is what happens when you don't realize you didn't push the right branch to try and thought it was green :headsmack: fix incoming once the right try is green.
