Transcript Auto-scroll Stability
Why
Users who turn off transcript auto-scroll expect the visible conversation to stay fixed while new content arrives. Chrome can still adjust the view through its native overflow anchoring when the toggle is disabled from the bottom. Separately, the clarification-recovery regression test must reliably observe the asynchronous hand-off it is designed to protect.
What
- A disabled native transcript auto-scroll preference prevents browser scroll anchoring from moving the transcript when appended content arrives, including when the user disabled it while already at the bottom.
- Re-enabling auto-scroll retains the existing catch-up behavior.
- The clarification-recovery concurrency regression waits for its asynchronous completion signal within a bounded interval instead of treating scheduler timing as a product failure.
Scenarios
- GIVEN an overflowing native transcript at its bottom with auto-scroll
disabled, WHEN a new message is appended, THEN the transcript's
scrollTopremains at the pre-append position. - GIVEN an overflowing native transcript with auto-scroll enabled, WHEN new content arrives, THEN the transcript remains pinned to the bottom.
- GIVEN clarification recovery has accepted its retry prompt, WHEN its asynchronous dispatch is scheduled, THEN the recovery call completes before the intentionally blocked prompt is released.
Out of scope
- Changing the transcript toggle's location, labels, or persisted preference.
- Changing clarification recovery production behavior or ownership rules.
