Image/movie scaling in the vertical direction wrong during pinning (Firefox and Chrome on Windows 7)

[pjcross]

Scale an image/movie to be larger, then pin it. The image scales in X, but keeps the larger Y size, filling the larger Y dimension with a long white region under the smaller scaled image. There is something wrong with the scaling in Y in general. When increasing the image size and then reducing it, If the mouse gets below the bottom edge of the image, the scaling starts drawing additional white space below the bottom of the image. Whereas with the X dimension, no white is ever added. I would expect that both X and Y should be scaling together instead of independently.
