Title in bossbar breaks HUD opacity

Any HUD icons made to be transparent using a resource pack will have full opacity when a bossbar with a "name" value is visible to the player.

Steps to Reproduce:

1. Enable the Bug Testing.zip resource pack attached
2. Create a boss bar

    /bossbar add opacity Opacity "Name" 

3. Make the bossbar visible to the player (Note the opacity of HUD icons)

    /bossbar set minecraft:opacity players @p 

4. Modify the bossbar to have an empty name (Note new opacity)

    /bossbar set minecraft:opacity name "" 

Observed Results:

Once the bossbar is made visible to the player, the opacity of all HUD icons will be changed to full.

Expected Results:

The HUD icons would preserve their opacity no matter what the bossbar's name is set to.
