Sample app that repros this bug

WKWebView does evaluate JavaScript after cookies have been cleared.
This is problematic because the completionHandler from the -[WKWebView evaluateJavaScript:completionHandler:] is never called.

Steps to Reproduce:
1) Run the attached code
2) Click on "wv1", that creates a WKWebView and loads a webpage
3) Click on "clear cookies", that uses the WKWebsiteDataStore API to clear cookies
4) Click on rc, that injects JS to retrieve the cookies from a web page.

Expected Results:
The completionHandler (from the JS eval method) is called.

Actual Results:
The completionHandler (from the JS eval method) is never called.

Version:
iOS9.0
