Understanding Size Differences in Livebook Smart Cells

The author, WoT_Abridged, has described a situation where they use the "Hidden Cell" Kino package by Brooklin Jazz for their Livebook. They are facing a problem with the smart cells expanding beyond the expected size upon evaluation, which creates a disturbance in the visual arrangement of their Livebook workspace. The author is seeking advice on the cause of this expansion and how to modify elements such as margins and the smart cell's height to maintain their desired layout. Despite examining Brooklin Jazz's CSS, they have not found the root cause of the increased sizing. They’ve also provided a visual example to illustrate the discrepancy between the smart cell and a normal Elixir cell.
