1. Open https://l.engage.covetruspharmacy.com/custloads/1046323924/md_147976.gif Result: On a slow network, only a few frames of this image will animate. 2. Wait a few seconds 3. Close the window 4. Open the same link again Result: In the second time all the frames of the image will be animated. 5. Empty the caches (empty the web site data) 6. Close the window 6. Open the same link again Result: On a slow network, only a few frames of this image will animate. This is a regression of the BitmapImage refactoring 276827@main. See bug 273457. We used to postpone animating the image till loading the image is complete. The number of frames can only be known for sure when the loading the encoded data is complete. If we start animating before we get all the data, we may end up animating a small set of the image frames.
