Editors are relatively split on this option. For example, Google Docs has Enter = line break, but Notion has Enter = paragraph break. I think your point about consistency between Markdown mode and the rich text editor is fair, though.
I can’t reproduce this with your current steps, could you provide browser details and more detailed instructions or a recording? Thank you!
We’re working on some fixes to how inline code works in the editor, which should resolve this problem.
Good catch, I agree that’s unexpected. I’ll report to our team to fix.
