Doing a quick test I cannot replicate an instance of it not working … however I do get a warning as mentioned
- Created an element and attached a mouse click action.
- Created a new function with the code above.
- Created a persistent symbol by selecting element and choosing “New Persistent Symbol from selection”
Previewed in latest (stable) Chrome and it still works also to note if you untick the “Preload” as suggested by Jonathan the warning disappears.
