Rain fog appears inconsistently under certain blocks

Rain fog disappears noticeably when entering a well-lit roofed area (as intended, I suppose). But underneath some blocks the rain fog still appears, whilst under other blocks the rain does not appear.

I don’t know that these blocks have in common but I’ve tested a few and here are some I think might interact with fog incorrectly:

• rain fog still seems to appear when player is under

  • oak trapdoor (open and closed)

  • carpet

  • glass

• rain fog does not seem to appear when player is under

  • cobwebs

  • leaves

There may be more blocks in this list, I have not tested all by any means.
