[Meta-issue] Intl operations returning incompatible results on Windows: investigate whether causes are strictly External

[dilijev]

The cause or partial cause of many of these issues may be WinGlob. Waiting on completion of #2919 (implement Intl with ICU) to get a better handle on the symptoms and causes.

Determine whether issues are intrinsic to the external library (WinGlob) or whether can be fixed (legitimately or by workaround) in ChakraCore directly.

See related linked-back issues below (also, I closed these issues to keep issue tracker tidy).
