The preview in the timeline for video with an alpha channel is weird. The alpha channel is neither used correctly nor simply discarded.
The testcase here consists of frames that are all one RGB color, but have varying alpha, so that there should be a number shown in the upper right corner. The thumbnail view and the preview window both show this correctly, but the timeline does not. If the timeline were simply discarding the alpha channel, it would show solid colors. Instead it shows something strange.
