Input from pen/stylus

Users on iPads can use Apple Pencil to write in normal text input fields in our application (transparent integration using Scribble). However, they are unable to write with the pencil in a CodeMirror field that is integrated into the same application (CM version 5.39.0). Is there a way to enable Apple Scribble for CodeMirror? Ideally any pen/stylus, of course, but iPad would be a first step.

This is probably never going to work in version 5.x. You could take a look at the 6 beta to see if that works better.
