PS4 dualshock controller not working with Minecraft 1.13-pre

PS4 dualshock controller no longer working with Minecraft (1.13-pre)

 

I use DS4Windows to map my PS4 dualshock controller buttons to keypresses used in Minecraft PC/java edition.  This has worked (and continues to work) with every Minecraft version prior to the Aqua Update snapshots.  Minecraft 1.13-pre, however, doesn't recognize any of the DS4Windows keyboard emulation configured to my PS4 dualshock controller.  When I try to map the controller directly to Minecraft under Minecraft Options.../Controls..., every button on the PS4 controller generates the same scancode.256 entry in the Minecraft Control mappings and Minecraft doesn't respond to the controller in-game.  This bug was reported in November 2017 for aquatic update snapshot 17w45b, and I am dismayed to find it still not fixed in 1.13-pre.  This must be fixed!  Please, either re-instate support of keyboard emulation by 3rd-party game controller profilers, or build in native support into Minecraft for the PS4 dualshock controllers (USB and Bluetooth).
