Breaking animation is more transparent when mining ice or stained glass

The Bug

When mining ice or stained glass, the breaking animation is less opaque than when breaking other (non-transparent) blocks.

Steps to Reproduce

• Place down a dirt block, begin breaking it, and pay close attention to the opacity of the block cracks as you do this.
• Place down an ice block, begin breaking it, and once again pay close attention to the opacity of the block cracks as you do this.
• Take note as to whether or not block cracks appear more transparent when mining stained glass or ice.

Observed Behavior

Block cracks appear more transparent when mining stained glass or ice.

Expected Behavior

Block cracks would not appear more transparent when mining stained glass or ice. Instead, block cracks on all blocks should have the same opacity.
