Make the "aspect ratio unlocked" button look unlocked

In the Image Size panel, there is a link icon that toggles whether or not the aspect ratio will be preserved when the image is resized. In its unlocked state, the icon shows a linked chain, which implies that the aspect ratio is locked. In its locked state, the exact same icon has a highlight around it. This is dumb. Please change it so the unlocked state clearly shows a broken chain.
