Created attachment 146401 [details] ROLLOUT of r119744 Any committer can land this patch automatically by marking it commit-queue+. The commit-queue will build and test the patch before landing to ensure that the rollout will be successful. This process takes approximately 15 minutes. If you would like to land the rollout faster, you can use the following command: webkit-patch land-attachment ATTACHMENT_ID where ATTACHMENT_ID is the ID of this attachment.
I think perhaps if you want to have a unit test with an io surface layer your context needs to pretend to implement at least some of the extension. I didn't look in great detail, though.
