It's not a big deal if we fix this later, since this is not a huge problem, and won't cause a lot of pain.
I'm not sure what we are classifying as regressions. But if that includes obvious things we didn't consider carefully during the product-design phase or spec it explicitly, this definitely qualifies as one of those cases. The user is on the issues page of a particular project when they are using this feature. It doesn't make sense they would see searches for a totally different project. You are in a project context. You shouldn't see anything in the UI that doesn't relate to it.
Thanks @MadLittleMods for putting this together so quickly. Let's go through the regular development flow, with code review and merge. So this should be 9.3 then since we are just passed the 9.2 freeze right?
