fix: SSR app does not work on Mac Safari - but works on Chrome

[walsha2]

Chrome

Run any basic SSR app as normal and compare the instance opened on Chrome and on Safari. I keep seeing this console message in the Chrome browser:

Refused to execute script from 'http://localhost:4322/main.dart.js' because its 
MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

However, everything seems to work fine on Chrome. The server/client side code work as expected.

Safari MacOS

With the app still running, open in a Safari browser on MacOS. Things are more catastrophic here and the server actually responds with a 500 (Internal Server Error).

The Content-Type warning may be a clue as to why this may be happening and why the server error only happens on Safari.

Browser Console

[Error] Failed to load resource: the server responded with a status of 500 (Internal Server Error) (app.client.dart.bootstrap.js, line 0)
[Error] Refused to execute http://localhost:8080/@http://localhost:8080/components/app.client.dart.bootstrap.js as script because "X-Content-Type-Options: nosniff" was given and its Content-Type is not a script MIME type.

Yea I think so. We can close this issue in favor of that.
