Karabiner-Elements: Latest Karabiner Elements driver update breaks inserting symbols in VSCode

Updated to latest VSCode and updated the driver.

Now I have a massive regression where in VSCode with Karabiner on, I can’t enter some characters.

Above image is perfect example. With karabiner elements quit, when I type the as above, it works.

With karabiner elements on, it will always eat the h character no matter what.

I can replicate this 100% of times and its a massive issue as I can’t type properly now now that I updated to latest Karabiner.

I also at first opened issue in VSCode issue tracker: https://github.com/microsoft/vscode/issues/192707

But it seems now the issue is fully on Karabiner Elements and its new driver.

Please help resolve this regression.

I initially noticed it when I tried to enter my console.log() binding with karabiner. From this config
