Comment highlighting breaks on closing curly

[hooke]

Well, the problem is clearly seen from the screenshots below.

I couldn't find any strict recomentation for JS to break the line after the closing brace. JSHint doesn't generate any warnings too.

I've tried to replicate this issue, but I didn't get the result as in the screenshot. Send me a gist with more source code so I can test this.

This is the example gist: https://gist.github.com/hooke/cd52a602c94f97ce750d
In gist comments are highlighted correctly.
In my vim with vim-javascript-syntax plugin it looks like:

Same problem as @hooke. Very confusing because even though the code is actually commented out, the syntax highlighting makes it appear as if the code will run.
Note that I only encounter this issue when using a multi-line comment /* */ and NOT a single line comment //, and then typing a closing curly bracket }
