Current behavior
Jest code coverage is apparently checking also tested CSS in the style tag

Expected behavior
Jest code coverage shouldn't consider the style tag, or even the template tag, as code to be covered because it is not part of the component logic.

Minimal reproduction of the problem with instructions
There's probably no need for a reproduction, the image should be fine

What is the motivation / use case for changing the behavior?
CSS is not part of the component logic
