I don’t think I implied that it was a bug here, which is why I placed this in the feature request category before it was moved to help. Or did I accidentally place it in the bug category?
Obsidian uses markdown as its format, but it’s by no means tied at the hip to the spec. It has, for example, an option to make single line breaks enough to create a line break Core even though this isn’t to spec.
I wasn’t aware of the concept of “loose lists” being part of the MD spec, but I would personally love a feature that would disable the “loose list” functionality so that lists broken up by a line break could be considered distinct lists, as I personally find that functionality super annoying. I know others do as well (see How to have a line break between list items without turning the list into a "loose" list, for example). Personally, this is one feature from more typical word processors that I miss.
