Steps to reproduce the problem:
1. add some console log statements to your code with a text prefix that so you can easily search for it; I do `console.log('MAXMAXMAX:', someVar);`
2. code must use workbox (my app seems to be using workbox v3.1.0)
3. open app and dev tools/console
4. type (eg) 'MAXMAXMAX' in the console filter

What is the expected behavior?
only lines containing 'MAXMAXMAX' should be displayed

What went wrong?
There are (also) lots of workbox statements, eg:

​​workbox Precaching is responding to: /app.min.js
workbox-core.dev.js:433 workbox Precaching is responding to: /analytics.js
workbox-core.dev.js:433 workbox Router is responding to: /data/routes.json
workbox-core.dev.js:433 workbox Router is responding to: /data/tours.json
workbox-core.dev.js:433 workbox Using CacheFirst to respond to '/data/routes.json'
workbox-core.dev.js:433 workbox Using CacheFirst to respond to '/data/tours.json'
workbox-core.dev.js:433 workbox Precaching is responding to: /manifest.json
workbox-core.dev.js:433 workbox Precaching is responding to: /images/manifest/icon-144x144.png

(don't blame me for the formatting - copy/pasting from chrome console has been very broken for years. ctrl-a didn't even work in this case)

Did this work before? N/A
