ea.com: top bar separates when scrolling down any page, causing a tear in the
UI

Reviewed by Anne van Kesteren.
There are two issues here:
1. paint performance is suboptimal as we scroll and we take upwards of 18ms,
2. we are running separate animations that we would hope to be in sync but
cannot be because
one is accelerated and the other isn’t and a gap shows. Due to our
architecture for running
such animations, one will run at 120fps and the other one will top up at
60fps.
We address this bug by introducing a quirk to disable the `transform`
accelerated animation
targeting the `<ea-network-nav>` element on all ea.com pages.
