Hello devs, and thank you for this great polyfill.

I am facing a strange bug in IE 11 (on Browserstack, no access to and old Windows system).

In short, the behaviour of preProcessedHeaders.split(/\r?\n/).forEach(...) seem to be inconsistent between for instance Chrome's last version (my reference point) and IE11 on Browserstack.

IE 11 -> Incorrect

Chrome -> Correct

Meaning that the polyfill simply doesn't work for me on IE 11.

If you want to try yourself assuming you have an access to an IE 11 browser:

'preProcessedHeaders'.split(/\r?\n/)
'preProcessedHeaders\n'.split(/\r?\n/)
'preProcessedHeaders\r'.split(/\r?\n/)
'preProcessedHeaders\r\n'.split(/\r?\n/)

Is anyone able to reproduce this?

Thank you for your time in advance.

Note
Polyfill version: 3.0.0
Here is the IE11 build I tested with:
