Weird bug I found. It seems that the y-rotation doesn’t work when attached to an persistent symbol, but only in FireFox. I’ve made a test case: https://oneuppedgames.com/clients/hype/rotation/ It’s seems consistent on all FireFox-browsers (both Mac and Windows). All others (IE, Edge, Chrome, Safari) seem to work.
The right is simply an image, the center is a regular symbol and the right is a persistent symbol. It’s all the same image, and the same animation (y-rotation from 0 to -360). The symbols have no content (except for the image).
Any idea? The source is here: https://oneuppedgames.com/clients/hype/rotation/rotationBug.zip
