If a media query contains comments, the busting process is currently cancelled with a "Cannot read property 'property' of undefined" error.

For example:
@media only screen and (min-device-pixel-ratio: 2) and (min-resolution: 2dppx) {
    /** Just a comment */
    .large-image {
        background-image: url('assets/image1.jpg');
    }
}

Support both versions of including videos using standalone video tag and using video tag in combination with source tags.

Option 1
<video><source src="video.mp4" type="video/mp4" /></video>

Option 2
<video src="video.mp4"></video>
