Large javascript file has incorrect mimetype

[ymor]

What is your Scenario?

When using testcafe against firefox/safari, so using the hammerhead proxy. One of my js files is incorrectly been served as text/html which firefox is blocking. The only difference in this file to the others is its quite large. I've created a contrived example at https://github.com/ymor/test-cafe-issue

What is the Current behavior?

What is the Expected behavior?

Actually not convinced its due to size. After doing some tweaking to dependencies I've got the file down to 709kb on disk and its still an issue.
