This doesn’t happen on my end

It does on my 0.9.3, under no influence of CSS.

In fact this is not the only inconsistency between Preview and Edit. I reported auto-renumbering issue of numbered lists which happened to Editor view (but not Preview) on 0.9.1, not under influence of CSS. The issue still exists today (0.9.3).
