===== BISECT JOB RESULTS ===== Status: completed ===== SUSPECTED CL(s) ===== Subject : Activate complex text path on Android Author : drott Commit description: In Chromium commit 10749067720a341 catapult was rolled, switching to default teardowns between pageset repeats, compare [1]. Activating complex text on Android again after this change in order to see how measurements are affected by this. If no memory regression shows up in the memory health measurements for memory pagesets this would indicate that we may have a memory-leakage over time problem in webview single-process mode but no issues in the usual tab process lifecycle on Android. Activating and TBR'ing to collect bot results, potentially reverting later if needed for further investigation.
