Stained glass, ice, slime block and other transparent block particles are not transparent anymore

The bug

Breaking stained glass now results in solid particles instead of transparent ones like in 1.13.

From k_wins_it:
In Minecraft 1.13.2, when you break a block which is semi-transparent, (like blue stained glass) the block break particles are also semi-transparent.

In Minecraft 1.14.2, the block break particles are not semi-transparent.
I have tested Minecraft 1.14 and 1.14.2. Both have this issue.

Please see my example images.

• 1.13.2 (working correctly)
  
• 1.14.2 (broken)
  

(I have a resource pack on which does not affect the bug in any way.)
