Measurement only, not for merge. Injects a 45 ms stall on every timeline scroll step and runs the virtualized arm of the viewport gate 10 times on CI, to measure how often the gate (with its one rerun, #4855) fails the stall. Closed once the numbers are read.

Edit accuracy: 557 passing here, 557 on the base branch

The gate passes.
Smoothness is reported in the artifact, not gated. A case fails only if it fails 2 of 3 runs.

Measurement done: 20 of 20 stall attempts failed the gate; the numbers are in #4855's body.
