If you press 'escape' to cancel the load while a large image is downloading and decoding (for example, the flickr page linked in the URL field), then scroll up and down to cause redraws of the image, the image disappears. This works properly in 3.6. This is a regression of bug 87739.

Thanks Matt! This is a decode-on-draw regression.

I'm going to guess that this is the result of us freaking out when we run out of data and going into error mode. Marking this as depending on bug 514033. If this problem is still around after that, we'll revisit it.

I think this is in the same area as another issue I have noticed. When you click on a link before an image has finished loading the image will result in the same problem, sometimes even immediately replacing the image without any scrolling. It is annoying when this happens and the page doesn't actually change for a few more seconds due to slow internet speeds. Its difficult to tell if its still there due to bug 583825.
