Moving tabs with non-default user context between windows needs rework
As part of bug 1242644 (about to land), swapFrameLoaders will start to enforce that both frames being swapped have matching OriginAttributes before allow them to be swapped. This breaks moving tabs between windows (which uses swapFrameLoaders) for tabs with non-default user context IDs. (Regular tabs using the default context continue to move as expected.) Most likely the issue is that the user context ID needs to be set earlier on the target browser we swap into when moving tabs.
