Root cause (mobile-only, never reproduces on desktop): .messages CSS resting overflow-anchor is 'auto' on touch devices but 'none' on hover+fine-pointer desktops (style.css media query). When _restoreMessageViewportAnchor writes scrollTop to realign the reader's anchor row AND content height above the viewport changed in the same frame, a mobile browser's native scroll-anchoring ALSO shifts scrollTop -- the two compensations stack and yank the reader to an unrelated earlier turn. Desktop never has the browser layer, which is why this reproduced only on phones. Fix: _suppressBrowserOverflowAnchor() sets overflow-anchor:none for the JS scrollTop write, releases (restores prior value) next frame. Engages ONLY when computed value is 'auto' (mobile) -- pure no-op on desktop (already none). Verified on isolated debug instance (mobile-viewport Playwright): - mobile auto: 800px above-viewport growth compensation 800px -> 0 (browser layer suppressed) - desktop none: helper returns null, inline value untouched (byte-identical behavior) - streaming: real turn, mid-read follow, 0 jumps, content held - scroll-regression suite green |
