When I try to compile this code:

const a = /\p{Letter}/u

the REPL crashes with the error /repl.js: Unknown property: Letter:

I have no settings enabled, except present-env + ie11 (to force the compiling of unicode regexes), and I'm on the latest version (but I tried with all the other available in the UI and they all break)
