   5 // This whole test runs as a separate browser_test because it depends on a
   6 // static initialization inside third_party/icu (gDecimal in digitlst.cpp).
   7 //
   8 // That initialization depends on the current locale, and on certain locales
   9 // will lead to wrong behavior. To make sure that the locale is set before
  10 // icu is used, and that the "wrong" static value doesn't affect other tests,
  11 // this test is executed on its own process.
