Hi! At our company, after transcrypting the code, we bundle javascript using Closure Compiler.
This new splitlines function causes this error:

ERROR - [JSC_UNTRANSPILABLE] Cannot convert ECMASCRIPT_2018 feature "RegExp Lookbehind" to targeted output language.

The problem is on str.split(/(?<=\n)(?=\n)|(?<=[\r\n])(?=[^\r\n])/g).

Solution could be just reverting to transcrypt==3.9.3.

But I leave here a patch for org/transcrypt/__builtin__.js, just in case you want to consider to modify it for future versions (see attached transcrypt-3.9.4.patch).

Also attached you can find transcrypt-3.9.4-splitlines.js, which runs some tests over both versions of splitlines(), getting consistent results.

I hope it helps. Thanks for your work!

The patch

transcrypt-3.9.4.patch

The tests

transcrypt-3.9.4-splitlines.js
