Dead Coral and Dead Coral Fans are treated as Solid blocks for the Script Brush

[barren basalt]

Axiom Version 4.5.3
Windows 11, Minecraft 1.21.4
Editor Mode (Script Brush)

Was working with the Script Brush to make a tool for pasting another block with a custom model at variable distances under specific conditions, and it was working strangely with dead coral fans.

What I expected to happen: The script brush would not place the blocks above dead coral fans we are using in the map.
What actually happened: The script brush placed blocks above the dead coral fans.

Steps to reproduce

1. Place Dead Coral and normal Coral variants
2. Use a script brush that places a block above solid blocks such as

if isSolid(getBlock(x,y-1,z)) then
setBlock(x,y,z,blocks.diamond_block)
end

3. See that blocks are placed above dead coral and dead coral fans and not normal coral variants

Recreatable? Yes
Attached are images before and after using the above example script.

(Originally this was just about Dead Coral Fans but curiosity got the better of me and I checked normal Dead Coral too, and I found it has the same issue)

Mojang has marked them as being solid

Huh. Well thats weird and annoying

[exotic star]

It looks like they copy pasted the coral blocks but didn't remove the line for it to be solid

[barren basalt]

Well, I guess this'll go to their bug report center then, thanks for checking this

Problem is I doubt you'll be able to get them to change it since it's hard to justify a vanilla gameplay impact

It makes some interactions weird, but isn't critical or game breaking

Worth a shot. It looks like its literally removing 10 lines of code to fix it

Almost certainly going to get removed by the moderators
