Expected Behaviour

Watch correctly handles circular dependencies

Actual Behaviour

Currently when circular dependency happens between more than two files, rollup hangs when watcher wants rebuild library.

In example project run: "npm run start" and when build is done, try to change "file2.ts" for example.

Based on my investigation fetchModule enters with isPreload === true and goes into handleExistingModule. That ends with await loadPromise and freeze.

It does not happen when first build is done.
