MapDataEvent#isSourceLoaded always returns false

[mollymerp]

Could this be because the data event (which triggers the sourcedata event) is fired immediately before the source.load event changes SourceCache._sourceLoaded to true ?

I thought that was the case, but a quick gut check to switch the function calls didn't change the result. But still it might need to be addressed after we figure out 👇 .

I think the root cause is that isSourceLoaded is set right when addSource is called via setEventedParent so sourceCache.loaded() is invoked only once, not every time the event fires like I believe was the intended behavior ??

I agree with this diagnosis. Nice 🕵️‍♀️ work.

I am having this issue with tilesets where data event never reports the layer as isSourceLoaded = true; Any advice on how I can achieve detecting when a tileset layer is fully loaded? I've spent days trying to find a solution and none work.

@risharde I have the same problem, did you find any solution?
