[css-animations] animation-iteration-count: infinite and animation-duration: 0s

 Hi,  While we're tying up loose ends in CSS animations, what is the behavior  of the following?     animation-duration: 0s;    animation-iteration-count: infinite;    animation-fill-mode: both;  The problem arises because when we come to calculate the active duration  of the animation we get:     active duration = 0 * infinity = indeterminate form  In Web Animations we came across this situation and considered some  possibilities:     a) let active duration = 0 -> final key frame value is shown,  start/end events are dispatched     b) let active duration = infinity -> initial key frame value is  shown, start event only is dispatched     c) it's invalid -> nothing is shown, no events are dispatched  Currently, the spec says (a)[1] but when we discussed this recently we  decided (b) is probably preferable.[2]  We liked (c) too but it complicated the model and the API since it  involves more checks for this particular edge case.  What do you think?
