WebGL and ECS

Should it work?
Tried the Samples Project ( https://github.com/Unity-Technologies/EntityComponentSystemSamples ) Using 2018.3.0b7.

I tried the Boid Example.
In the editor, the fish boid won't instantiate when the platform is WebGL.
In the browser, the fish are instantiated, but I get errors regarding JobTempAlloc every frame.

Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak
To Debug, enable the define: TLA_DEBUG_STACK_LEAK in ThreadsafeLinearAllocator.cpp. This will output the callstacks of the leaked allocations

Is it like this in every version of the Unity Editor or the ECS packages? Or is there a combination that does work?

Thanks

 

I wouldn't be surprised, if ECS is not yet complaint with WebGL.
Unless someone confirms as such, I think we may still need to wait.
Or maybe there is simple fix already?
