Drag unresponsive inside Adobe CEP html engine on Mac when using the Leva UI library

Drag unresponsive inside Adobe CEP html engine on Mac when using the Leva library: https://github.com/pmndrs/leva

Leva uses the "use-gesture" library to handle drag and drop. These libraries are functional with my Windows installation of Adobe products and function in all browsers I've tested but they are unresponsive when ran on a Mac installation of Adobe products.

After contacting the owner of the "use-gesture" repo, he suggested this might be due to the Adobe CEP html engine not supporting pointer events. It looks like other people have had Mac specific issues due to unsupported pointer events:
