Repro steps

1. Create a basic Angular project
2. Enter the project folder
3. Generate a library
4. Test that library & create code coverage
5. Open the coverage HTML
6. Navigate to src/lib/ and then any file (in my screen shot, I chose test-lib.component.ts)

ng new test-lib-app
cd test-lib-app
ng generate library test-lib
ng test test-lib --watch=false --code-coverage
open coverage/index.html

The log given by the failure

Desired functionality

Code coverage should be 100% and the highlights should not include portions of the strings in the import call, icons around the code, etc.

Mention any other details that might be useful

No other details.

Whatever the problem is, Issue #11672 will likely deal with it, so I'll close this Issue.
