Chance: $skip should skip the images but keep other styles.

[ialexi]

When you use $skip to skip a slice, Chance should still style the skipped slice, but should "skip" the image. Currently, it will skip styling entirely.

The common case for $skip is when you are overriding a button style: when styling a capsule button, you don't need to replace the middle slice, so you skip defining it; instead, you only override the left and right slices. However, when you do so, you may also change the size of the left and right slices. If the middle slice is skipped in its entirety, it will still have the wrong size.
