Ensures tabs and collapsibles render in version diff

Editor assessment

The subject states the rendering fix plainly: tabs and collapsibles now render in the version diff view. The affected view and the previously missing elements are both identified without opening the diff. The feat type is defensible for restoring display capability even though fix would fit; the rubric tolerates straddling choices. No scope or body explains how the diff view previously collapsed these containers — a modest gap — but the message stands alone. Style is clean: no trailing period, no junk, no footers. Good and publishable.
