bug HTML5- isFalling condition- platformer automatism

I am using the platformer automatism’s isjumping and isFalling conditions to trigger animation changes.

What is strange is that the animation switching works just fine for native mode and works about 50% of the time in html5 mode.
Html5 mode does not always trigger the animation change when the isfalling and isjumping conditions are true.

It is perhaps worth noting that in my case I have slowed down the falling speed to 200, in order to simulate lower gravity.

still present in 3.3.71

It might have something to do with this (from terminal)

Initializing RuntimeScene from layout... Loading RuntimeScene from a scene.....ERROR: Unable to create shared data for automatism "Platform".ERROR: Unable to create shared data for automatism "PlatformerObject"... Done.
