Not a consistent failure, but lots of flakes, including at least:
external/wpt/longtask-timing/longtask-in-sibling-iframe-crossorigin.html
external/wpt/pointerevents/pointerlock/pointerevent_pointerlock_supercedes_capture-manual.html
geolocation-api/maximum-age.html
http/tests/devtools/layers/layer-compositing-reasons.js
http/tests/websocket/multiple-connections-throttled.html
virtual/scroll_customization/fast/events/touch/gesture/gesture-tap-hover-state-iframe.html

These should be filed as separate bugs and triaged + disabled (at which point this catchall bug could be closed); I don't have time, so leaving for next sheriffs.
