pathToEmotionCacheProps option doesn't seem to work after build

[ginokok1996]

I've set a nonce via the described emotion cache prop route. This is working just fine when developing with npm run develop.

The stylesheets are correctly receiving the nonce. But when i do a npm run build and then npm run serve the plugin doesn't seem to work anymore. My stylesheets now wont receive the nonce making my csp headers block the styling.
