Preserve aspect ratio in ableton: plugin only gets smaller when dragged by the borders

Hi I am using getConstrainer()->setFixedAspectRatio(); in the constructor of the audioprocessoreditor, and this is working great for the standalone and reaper, but in ableton when the plugin is dragged by the border, the plugin can only be resized to a smaller size, but will not get bigger. Is this a known issue to someone? Is there a fix?
