Upgrade bundled Chromium from v126.0.6478.184 to v143.0.7499.169 to match the renderer browser version. Update sec-ch-ua header from v123 to v143 in direct font request headers. PPLT-4214 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Chrome >=128 new headless auto-requests /favicon.ico on page load, breaking discovery tests that asserted exact request counts. Filter at the helper level so all tests benefit without per-assertion churn.
Chrome >=128 new headless enforces site isolation via IsolateOrigins and site-per-process, putting cross-origin sub-resources and worker fetches into separate renderer processes. The existing --disable-site-isolation-trials flag only covers opt-in trials and no longer keeps everything in one renderer. Extend the existing --disable-features list with IsolateOrigins and site-per-process so the main page's Fetch.enable / Network.enable listeners continue to see cross-origin and worker traffic, matching the v126 old-headless behavior Percy relies on. Also add HttpsFirstBalancedModeAutoEnable to prevent new headless from blocking HTTP asset discovery with ERR_BLOCKED_BY_CLIENT.
Invalidates actions/cache entries that still contain the old v126 Chromium binary so CI downloads the new v143 revisions fresh.
