Wide or tall tables, code blocks and display equations overflowed the reading
column and a scroll gesture over them turned the page instead of scrolling the
content (#4400).
- Wrap tables and display equations in a horizontally/vertically scrollable
container; route touch + wheel along the box's scrollable axis so it scrolls
the box and never turns the page, even at the edge (both axes).
- A box that fits its column is marked fit (overflow:visible) so it never clips
or captures gestures; the fit decision is measured once after layout via a
self-disconnecting ResizeObserver, so it never relayerizes during a page turn.
- The scroll wrapper carries a new cfi-skip attribute that makes it transparent
to CFI: epubcfi.js hoists a cfi-skip node's children into its parent (unlike
cfi-inert which drops the subtree), and xcfi.ts mirrors this for CFI<->XPointer
so existing highlights, bookmarks and KOSync positions inside a wrapped table
or equation still resolve. The sanitizer whitelists cfi-skip.
- Bump foliate-js submodule (cfi-skip support + raf fallback for large sections).
