The comments icon on each Short used to open the full /videos/{id}
page, kicking the viewer out of the vertical feed. Now it opens a
shared side drawer on desktop (right edge, 420px wide, starts below
the header) or a bottom sheet on mobile (70vh, slides up from the
bottom nav), without leaving the feed.
Content is the same resources/views/components/video-comments
section rendered on the watch page — fetched as XHR and the whole
#ytcSection node is lifted into the pane. All the existing comment
features (replies, likes, translate, heart/pin, permalinks) work
identically because we're reusing the exact same DOM.
