Description Chris Dumez 2016-03-14 10:35:24 PDT
We have experience a huge regression on Mac PLT after <http://trac.webkit.org/changeset/197981>: (rdar://problem/25113391). So disable the feature until the performance issue is resolved.

Reverted r198145 for reason:

This attempt to disable the feature did not fix the PLT regression
