CSS special selector ":host" only work first time #1845

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 5.4.0
• Cross-platform modules:
• Android Runtime: 5.4.0
• iOS Runtime:
• Plugin(s):
• NativeScript-Angular: 7.2.4
• Angular: 7.2.15

Describe the bug

The :host css selector only works first time, after that that the selector is ignored for the component.

To Reproduce

• Use :host in a components stylesheet.
• Use the component more than once.
• The style is ignored.

Expected behavior
I'd expect the style to be applied to every instance of the component.

Sample project

I've made a small project with a ListView and an item-component here:
https://play.nativescript.org/?template=play-ng&id=NXYfcY&v=15

All the items should have: background-color = green, color = black, text centered, font-weight = normal and padding = 8.
But only the first item looks like that the others have: background-color: blue, color = white, text right aligned, font-weight = bold and no padding.
