It worked perfectly in 5.0.0-alpha12, but since then it got broken in 5.0.0-alpha14.  
What happens now is zoom-in doesn’t work (has no effect), and zoom-out zooms out at insane speed.  
Browser used is Mozilla Firefox 86.0.  
The faulty commit seems to be: [Minor fixes for IE 11 support (DeviceInputSystem) (#10013) · BabylonJS/Babylon.js@48f2cb9 · GitHub](https://github.com/BabylonJS/Babylon.js/commit/48f2cb9c08769ff13ffff41edc55bad1fc9ef8b2#diff-45b2043da48cb4223d456ae562b2b3a6241d7093f7aced73e0e7000b5c71ccdb)

It seems the problematic changes were already reverted in this commit: [Revert Arc Rotate wheel changes · BabylonJS/Babylon.js@2fda47f · GitHub](https://github.com/BabylonJS/Babylon.js/commit/2fda47fad7262dfe9a755cd2b3f1f411a825b015)

So I am waiting for next version to try.
