Its fake predicate turned true 95 ms after the page was made and the test wanted at least 4 slices of 30 ms. On a loaded
machine the 30 ms timers fire late and merge the slices: the 0.2.0 candidate's full pass got 'sliced (3 calls)'. A
preload that blocks the event loop 9 ms of every 12 reproduces it 5 of 5 times. Now the predicate holds on the 4th call:
exactly 4 calls, each with the same predicate, args and polling, each slice 0–30 ms, and the wait lasted the three
slices (≥ 85 ms). It passes 5 of 5 under that lag and under 25 ms of every 27. A helper that stops at the first
timed-out slice still fails it. A test timing flake, no product change; golden unchanged.
