Tested. Found next issues:

1. When the modal is open, the scroll continues to work
2. Modal from service described as static in its body, but it's not static.

[YevheniiaMazur]

Tested. Looks good now

[SergeyKuryatnick]

Tested, looks good.

Notice: two unit test are failed

Hi! How can i encapsule my modal component. I dont want to write moal header body.. other element in my component templete. I am using components normal pages. But sometimes i need to open them in modal other pages. I did its working well. But look like ugly. I want to encapsule my component templete another templete. Open component inside another templete. How can i do that?
