Custom theme causes issues

I made a very minute change to the default Vector theme and it’s showing the preferences like this now.

Here is the commit that causes the issue. Can someone explain why this occurs?

Looks like a Javascript or ResourceLoader error is preventing the tab widget from initializing. The commit link is broken so no way to tell what the error is.
