HTML5 - PhysXVehicles Support with Unreal Engine 4.15

From what I can see there currently doesn’t seem to be support for HTML5 packaging with the PhysXVehicles plugin as there was with 4.14 since this has moved to it’s own plugin and the plugin states HTML5 as blacklisted. Just wondering if that definitely is the case and if so, any work arounds, or any ideas when this is likely to be supported? Many thanks in advance.
