The Windows runner starts steps at I/O priority Low. The driver and the browsers inherit it, and Firefox storage flushes stall until tests time out. Reset the test steps to Normal, as microsoft/playwright#43707 does upstream.

Summary
playwright-x64-server2025-64-corerunner starts steps at I/O priority Low. The driver and the browsers inherit it, and Firefox SQLite flushes stall until tests time out (devops: Windows CI runs tests with low I/O priority, Firefox storage tests time out playwright#43704).scripts/windows-normal-io.ps1is upstream's helper without the Git Bash mode, which these steps don't need. The Windows test steps dot-source it first, so pytest, its xdist workers and the browsers run at Normal. The step log shows the change, e.g.Test launcher I/O priority: 1 -> 2 (Normal).Build (playwright-x64-server2025-64-core, 3.12, firefox)fails on every recent run of main with the same 30s timeouts upstream saw: persistent contexts, storage state,test_ST_005_should_round_trip_opfs, HAR and cookies (latest run).Verification
On this PR's run, every Windows test step logs
Test launcher I/O priority: 1 -> 2 (Normal).Build (server2025, 3.12, firefox)passes. The remaining Windows failure isBuild (server2025, 3.12, webkit), where a worker crashes intest_TR_023_should_produce_screencast_frames[webkit-fit-500-500]. That crash also happens on main (10-26, 10-24).
