It looks like it is intended that one cannot pillar with scaffoldings. Instead, another scaffolding is placed in the direction that I am facing at. I thought it may be possible to place a scaffolding on another scaffolding if all scaffoldings in this direction are placed.
Stand on a block which is no scaffolding with scaffoldings in your hand. Face down. Jump and place one scaffolding. Works like normal.
If you try it again, now on the scaffolding, the scaffolding is placed at one side and not at the top. This is intended and useful if there is no space to place a scaffolding on top of another, e. g. if you stand on top and the space is blocked. But if the space is not blocked, e. g. due to jumping, the scaffolding should be placed on top like any other block.
If this description is not understandable, I try to provide a video.
I am not sure if this belongs to here but the ticket I found is marked as a duplicate of this ticket though I think it is important to notice.
An armor stand starts to burn if someone hits it with a sword enchanted with Fire Aspect. A similar entity, the boat, cannot be ignited in that way, even though it is flamable (and drops than immediately). All was tested in 1.18.1.

I also encounter this bug at my single player world in 1.16.4.
