Angular 5.2.11 with Agular-CLI6.1.3 not working with IE9-11

[zhangjinsong]

I have a project with angular 5.2.10 and angular-cli 1.7.3 and I run into a same problem as [#111]. Even though i tried to uncomment all metioned lines in polyfill.ts i still had these lines:

the 1st line indicates the bug of "Fetch" (the hot-reload)

the second:

the last:

This is my polyfill.ts:

And my package.json:

Everything works fine on Chrome, Fifrefox, Opera, Edge,... but IE9-11. I researched and followed other similar threads but nothing helps.
I would appreciate it if someone helps me find out what is wrong with my project configuration. I will provide more details if needed.

[#111] is revised as [#11790]
