Description

Terser minifies js files in assets. I think it should not transform assets files in any way.
It's so strange that even disabling
"optimization": false,
"buildOptimizer": false,
doesn't solve the problem and js assets still changing

🔬 Minimal Reproduction

ng new ang8
copy attached file to assets folder and run
ng build --prod --aot

here is repro: https://github.com/quanterion/cli-assets-bug
you can see that files https://github.com/quanterion/cli-assets-bug/blob/master/src/assets/draco_decoder.js and https://github.com/quanterion/cli-assets-bug/blob/master/dist/ang8/assets/draco_decoder.js are different.

You can see attached file from assets changed in dist folder
and by minifing it Terser breaks it unfortunately:(

Is there temporary workaround to disable file minification, like adding comment at the top of the file?
