Two live defects at cadfba0, each with the repro that showed it and the fix that answered it: a span places the slot after a collapsed leftover child a gap early and a gap too long, and a child reused under a parent that redrew keeps the mask index that parent replaced, so its drawing is clipped where the subtree used to be. Neither is covered by a test, which is why the suite is green over both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
