If an image container is empty, it will not produce an image key for use with WebRender. This is generally not a sign of failure because the producer likely has yet to populate the container with data. As such, we should not immediately attempt to fallback. In fact, fallback can make things worse in this situation, as we will create an image client to send over the data, but then find that there is no data to share (or find that there is, due to a race with the producer thread, and use image clients when we could use shared surfaces).
