===== BISECT JOB RESULTS ===== Status: completed ===== SUSPECTED CL(s) ===== Subject : [perf] Change google.com to google.co.uk in top_10_mobile_memory and dual_browser page sets. Author : mythria Commit description: In the top10_mobile page set google.com gets redirected to google.ca. This sometimes causes problems in telemetry with scrolling. As a short term fix, replace google.com with google.co.uk in the page set. We cannot change it to google.ca because memory_top_10_mobile uses the same page set but with a different wpr that has a recording of google.co.uk. Updated dual_browser page set to be consistent with top_10_mobile page set. Also recorded new wprs for memory_top_10_mobile, dual_browser and top_10_mobile_memory.
