Installed PWA breaks due to '/?standalone=true' start_url since version 3.2.1

[FreekVR]

After updating to 3.2.2 I am starting to have issues with a freshly installed PWA which by default runs on ?standalone=true.

I'm getting 404s for several of my bundles in the console, as well as this message:

workbox-precaching.prod.js:1 
Workbox is precaching URLs without revision info: /?standalone=true
This is generally NOT safe. Learn more at https://bit.ly/wb-precache****

Due to the bundles not being loaded the app is essentially not working. I figure it's trying to load files from a previous build which no longer exist on the server due to hash changes.

It seems if I set my manifest start_url to simply / this resolves the issue, so the problem seems to be cause by the query param?

Hi. This issue should be gone with 3.3.0.
