Redstone components should possibly be exempted from being floating blocks, unless there's a nice way to solve this issue.

Oh, repeaters do it.

The issue occurs for redstone dust as well

They appear to update to me, is there a way to trigger this?

When I tried it on dust it worked fine.

Break the redstone torch after you float it

I placed the dust on a block, floated it, broke the block, and it updated just fine on landing.

I mean powered-wise. Maybe the bug has been resolved though. Let's speak in dev chat
