When using Confluence Cloud , the editor displays nice spacing between a H4 heading and the next line of text - but that disappears after publishing.
See YELLOW arrows in below snap
I prefer the editor spacing but most important is to have them be the same. WYSIWYG.

Similarly in the above snap , the GREEN arrows show how a new paragraph (fullstop > enter) appears in the editor with nice spacing down to the next line , but this also disappears after publishing to live.

I get the same outcome using Google Chrome on Windows, using Firefox on Windows, and using Chromium on Linux.
Is this configurable ? If not, could the folks who look after this aspect of the UI please look into it ?
