Steps to reproduce the problem:
Given a service worker that sends a postMessage to the active worker during installation (and waits for a channel response):
1. Open a bunch of tabs all within the scope of the service worker
2. Change the service worker file

The issue is intermittent. Chance of happening seems to be increased by using skipWaiting().

Example repo and video screencast of reproduction here: 
https://github.com/asakusuma/sw-postmessage-crash

Can't reproduce in Firefox or Chrome canary.

What is the expected behavior?
Tabs don't crash

What went wrong?
A tab (usually the first one opened) crashes.

Did this work before? N/A 

Does this work in other browsers? Yes

The issue does not happen on Canary. From looking at the chromium code, it looks the issue might have been fixed by this commit: https://chromium.googlesource.com/chromium/src/+/fa23f2ad198386c864ec998452d9f6d916b2219a

However, I'd like to understand the root cause of the issue and how to mitigate in chrome versions that have the issue.
