-# ============================================================================
-# worker-remaining  (2 tests)
-# Web Workers attach over the WebView backend now (Worker.enable is sent during
-# session init), so page/workers.spec.ts mostly passes. Two gaps remain:
-#  - 'should clear upon cross-process navigation' passes its own assertions but
-#    the cross-process target swap leaves the page in a 'Target closed' state for
-#    the next test (same root cause as target-closed-cascade above).
-#  - 'should support extra http headers': setExtraHTTPHeaders is not applied to
-#    the worker script request, so worker.js arrives without the header.
