aspect="auto" for px.imshow does nothing when plotting RGB data

I am trying to plot an RGB image that strecthes to fill the figure, and I cannot get it to work.

Using a standard 2D array works as expected, and the image is able to dynamically stretch to the figure.

arr = np.random.random((100, 100))
px.imshow(arr, aspect="auto")

But if I instead try to plot an RGB image with the same settings, then the image stays with its original aspect ratio.

img = np.random.random((100, 100, 3))
px.imshow(img, aspect="auto")

In this case, setting the aspect key does nothing and the image keeps a fixed aspect ratio. Explicitly adding with and height also does nothing to change the aspect ratio.

Is this an expected limitation of the aspect setting? If yes, then it should probably be documented.

从 issue 中的 px.imshow 示例开始，比较 2D-array 和 RGB-array 路径，重点关注 aspect="auto" 的处理方式。完成的标准是 RGB 图像能够按预期拉伸，或者记录该限制及其对宽度和高度的影响。
