.1 .0] Animated PNGs replace parts of the image that aren't redrawn between frames with transparency
User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20161208153507 Steps to reproduce: I tried to load an animated PNG that was optimized (meaning certain parts of the image are not redrawn between frames) using Firefox 50.1.0. Actual results: Parts of the image that are not redrawn between frames were replaced with transparency. Expected results: The non-redrawn areas should remain visually the same as in previous frames of the PNG, without turning transparent, until they are redrawn.
Can you attach the offending APNG, please. Anyway, I suspect it's a dupe of bug 1319025.
