../../chrome/browser/ui/web_applications/web_app_uninstall_browsertest.cc:320: Failure
Value of: shows_cct_after_uninstall
  Actual: false
Expected: true
VULNERABILITY CONFIRMED: ShouldShowCustomTabBar() returned false for an out-of-scope navigation in a TYPE_APP window whose app has been uninstalled. The window has no omnibox and now no Custom Tab Bar -- arbitrary content renders with zero browser-supplied origin attribution (PWA-window address-bar-spoof equivalent).
