It is possible for a draw to succeed, but a frame to still not be
submitted. This can happen when nothing blocks the draw, but still
no frame was submitted because there was no damage. In such cases,
mark the frame as deliberately dropped, rather than a frame that
was aborted while waiting on the main-thread.
