Nit: Would you mind to remove `**` at the beginning and end of your comment? I know that our coding conventions for [comments](https://github.com/adobe/brackets/wiki/Brackets-Coding-Conventions#comments) do not explicitly mention what can be and can't be in the comments. And I know you want to highlight the issue you want to solve in your comment, but it's better we don't have any comment with different forms of highlighting with extra `*`.
