VS code highlights jasmine functions in Angular 6

I've recently migrated to Angular 6.0. And VS Code highlights all jasmine functions as unknown. It works fine and runs tests successfully. How to let intellisense know about Jasmine?

In previous version some workaround worked:

import {} from "jasmine"

But it doesn't work any more.

Next import in test.ts also generates errors:

import 'jasmine';

Update: If I add "jasmine" to types in tsconfig.json - it does the trick. But it doesn't work with tsconfig.spec.json. I don't need this types in application bundle.
