Steps to reproduce the problem:
1. Go to a site with a service work with imports
2. Try to view imported script contents
3. 

What is the expected behavior?

What went wrong?
At the moment it's not obvious or easy to view the current contents of an imported file which is cached for a service workers use.

Would be handy to have the option in sources in DevTools

Did this work before? N/A
