User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 Steps to reproduce: Create an SVG filter with <feTurbulence type="fractalNoise" baseFrequency="0"/> or <feTurbulence type="fractalNoise"/> (because 0 is the default value for baseFrequency) and apply to an element. Actual results: Firefox returns a transparent rectangle. Expected results: For a turbulence filter of type="fractalNoise", the zero-frequency result should be 50% alpha 50% gray. This is probably an over-eager optimization, since for type="turbulence", the zero-frequency result is transparent black.
