[MC-162653] /fill to replace air not working in naturally generated caves/structures

When attempting to execute the command:

/fill ~ ~ ~ ~ ~ ~ block replace air

in a cave/mineshaft or underground structure it did not successfully execute, while I expected it to replace the "air" within the cave. When going to the surface or digging a hole into a wall the command works as expected.

Have you tried just /fill ~ ~ ~ ~ ~ ~ ice?

@Edvinas Katkus For what I was doing I needed to replace only air (and keep surrounding blocks) the empty "~" were just an example, for what I was making I was using larger areas.

The air there could be cave_air, although the world generator is not supposed to actually put them in the world. Probably a duplicate of MC-125135.
