Repro steps.

1. curl localhost:4200/assets/image.svg
2. Change that image slightly and save it
3. curl localhost:4200/assets/image.svg - will not show the change
4. Save a file like app.component.ts
5. curl localhost:4200/assets/image.svg - you'll see the change

Desired functionality.

Would like changes reflected without having to update a watched file. I'm currently debugging some weird SVG issues to do with feColorMatrix and was confused why changes weren't being shown. It wasn't until I saw the same issues in Firefox that I realised the problem was the server.

I also think assets should trigger a reload. As far as I understand the webpack-dev-server is holding the files in RAM, so also a manually Browser Refresh wouldn't show new versions of the files in the assets folder. Therefor a restart of the CLI is mandatory, which hurts a lot with an initial startup time of e.g. 40 seconds.

Other use case besides @intellix SVG example:
Using ngx-translate with JSON files for the translations in the assets folder.

This seems to be an unintended consequence of #7310, where another different bug was masking this bug.
