## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Issue and item detail pages use a shared issue chat thread to show comments, runs, activity, and interactions. > - That thread still defaulted to landing on the latest comment when messages first loaded. > - On long issue/item pages, that default can yank the operator away from the top of the page before they choose to inspect the newest message. > - Deep links to comment hashes can create the same kind of initial viewport jump when they are used as generic navigation targets. > - This pull request makes initial latest-comment and initial thread-hash scrolling opt-in instead of default behavior. > - The benefit is stable initial page position across issue-thread surfaces while keeping the explicit Jump to latest control available. ## Linked Issues or Issue Description No exact public GitHub issue was found for this bug. Bug description: - What happened: opening a page with a shared issue conversation thread could automatically move the viewport toward the newest comment/thread target. - Expected behavior: ordinary page loads should keep the initial viewport stable unless the user explicitly clicks Jump to latest. - Steps to reproduce: open an issue or item detail page with a long conversation thread and observe whether the page jumps to the newest thread entry on initial load. - Paperclip version/commit: reproduced while working on the current `master` branch lineage. - Deployment mode: local trusted/dev UI. Related public thread/comment UX work: Refs #3916, Refs #7972, Refs #8800. ## What Changed - Changed `IssueChatThread` so initial latest-comment scrolling defaults to off. - Added a separate opt-in for initial thread-hash scrolling, also defaulting to off. - Preserved stale deleted-comment hash cleanup without scrolling the page. - Updated regression coverage so default initial load stays put, comment hashes do not scroll by default, and manual Jump to latest still scrolls. ## Verification - `pnpm --filter @paperclipai/ui typecheck` passed on the clean PR branch. - `pnpm --dir ui exec vitest run src/pages/IssueDetail.test.tsx -t "loads from the pending state into issue detail without changing hook order"` passed on the clean PR branch. - `pnpm --dir ui exec vitest run src/components/IssueChatThread.test.tsx` was attempted on the clean PR branch, but the file fails before changed assertions with the existing `TypeError: act is not a function` test-harness issue across 58 tests; 14 tests passed. - Static check: no `autoScrollToLatestOnInitialLoad={true}` or `autoScrollToHashOnInitialLoad={true}` call sites remain in `ui/src`. ## Risks Low risk. This only changes initial scroll defaults in the shared issue thread. The main behavioral shift is that direct comment/thread hashes no longer auto-scroll on first load unless a caller explicitly opts in; the Jump to latest button and post-submit scroll behavior are unchanged. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
