'Statement Expected' Syntax Error Highlighting on First Line of JS File in PHPStorm

I have a JS file where no matter what is put on the first line (comment or code), PHPStorm lists a syntax error. When I hover over the error, the description says "Statement Expected". What it looks like:

Is this a bug with the IDE or something that can be disabled?
