ActionManager on mobile doesnt working at first click



I found a problem in the mobile area.
When I have a scene and click on an element with the Chrome mobile emulator. The field in the ActionManager “meshUnderPointer” is undefined. But if I move the scene minimally, it gets the right mesh. If I want to select another one, I have to move the camera minimally to select the new mesh.

I have prepared a PG. (Babylon.js Playground)
Start PG, select the mobile emulator in Chrome and click on the ground > Console returns undefined in “meshUnderPointer”.
Turn the scene a bit and then click again. Mesh was found.

How can i fix it or need the framework a bugfix?

Thanks guys.
