Hello, maintainer,
I have two strange bugs to report. I saw that the issue with loading a nil URL had been fixed before Fix nil url reloading, but it still exists on watchOS. Additionally, there's another issue on watchOS where the gif animation stops when I quickly switch URLs, which doesn't happen on the phone. I wrote a demo to easily reproduce this problem and created a file named FastSwitchGifView.
