When spatial scalability is used, both vpx and aom set key frame flag for all spatial layers of the first frame, while rtp code expect it to be set only on the frame without spatial dependencies. That creates confusion for the frame dependency calculator. Simplest solution seems to ignore that confusing signal and instead rely encoder wrappers update frame buffer usages when key frame is generated.
