Do you need this bit? I thought experimental features were on-by-default in
Layout Tests...

Do you mean I should revert everything in core/testing ?

[adamk, 2014/12/16 18:25:14]

Yes, sorry, that's what I meant to say. I think you'd only need it here if you
wanted to be able to turn it on and off from inside a layout test.
