map(atob) doesn't work without wrapper function

See original GitHub issue

RxJs version 5.5.2 (also in the docs page, in the console, same problem)

Code to reproduce:

Rx.Observable.of("eyJmaXJzdE5hbWUiOiJSYWZhbCIsImxhc3ROYW1lIjoiTWFzemtvd3NraSIsImVtYWlsIjoidGVzdEB0ZXN0LnBsIiwidG9rZW4iOiJ0b2tlbiJ9")
.map(atob)
.subscribe(console.log);

Expected behavior: should log "{"firstName":"Rafal","lastName":"Maszkowski","email":"test@test.pl","token":"token"}"

Actual behavior: logs error: Uncaught TypeError: Illegal invocation at eval (eval at MapSubscriber._next (0-Rx.js:5709)

Additional information: the problem I found in the source code is in MapSubscriber. The project function this.project is called via this.project.call(this.thisArg, value, this.count++); but atob doesn’t work if the thisArg isn’t null/undefined/window.

the correct way is

Rx.Observable.of("eyJmaXJzdE5hbWUiOiJSYWZhbCIsImxhc3ROYW1lIjoiTWFzemtvd3NraSIsImVtYWlsIjoidGVzdEB0ZXN0LnBsIiwidG9rZW4iOiJ0b2tlbiJ9")
.map(i => atob(i))
.subscribe(console.log);

could close this issue @kwonoj
