for context we began seeing g50+ failures on Mac wk1 from this change. This was causing ews runs to exit early for wk1.

The trick here, I think, is that moving them from Experimental to normal means they no longer get implicitly enabled by DRT. Previously, ReferrerPolicyAttributeEnabled was disabled by default in WebKit1, but enabled in DRT (along with all other experimental features). Now it's disabled by default in WebKit1, period, and the tests fail.

We've done a lot of work on tidying up preferences over the past year, so it seems like this can probably be safely closed?

[Brent Fulgham]

Oh yes! Thank you.
