Using rasterio to show RGB image with nodata

This question is same as https://stackoverflow.com/questions/59132459/use-rasterio-show-rgb-image-with-nodata

I have a multiband image with nodata value (which is Landsat and been set nodata to 0). And I want to use rasterio show the image,But I found that the show function cant deal the nodata value with multiband image. And I had test that singleband image is well.My code like this:

with rio.open(path) as src:
    arr = src.read([1, 2, 3], masked=True)
    show(arr)

the image is like this:

This is the landsat image,You can find that the image is warped by black color,In this place the data is nodata and would be display as transparent.

How do I show nodata multiband img by rasterio?

arr[arr==0] = np.max(arr)
show(arr)
