Block Outline Transparent Instead of Black and Colored Transparent Blocks Not Showing Clouds Behind Them

I noticed something weird about the block outline that appears when the crosshair is pointing at it. I then noticed it was transparent instead of black with clouds not appearing behind it. I thought it looked strange so I reported it. When I looked back at the footage that I recorded, I also noticed that the clouds weren't rendering behind slime blocks and honey blocks. I then tested it with glass and stained glass and I got the result of having the clouds showing behind stained glass and the clouds showing behind glass.
