When you set resize the page option (CTRL +) in FireFox 3.6.10 it resizes images the wrong way. There will be a new line added at the bottom of the image, but the line will be taken from the top of the image, not from the bottom, so it makes all vertical gradients broken.
Is this a new bug or was in older versions as well? Do they intend to fix it? Or maybe should I just make the gradiented images bigger than needed so it has more bottom lines to choose from?
