I've had some issues with sporadic double initialization of ICU when running
tests on my machine. Looks like this fix is good enough for
content_browsertests.

content_browstests has base::i18n::AllowMultipleInitializeCallsForTesting
already and content_main_runner has base::i18n::InitializeICU(). What specific
tests are you seeing this in?

Most of the DownloadContentTest.*, e.g. DownloadContentTest.DownloadCancelled.
It looks like on Android content_main_runner is not used for the main process,
but rather BrowserMainRunner is invoked directly from BrowserTestBase::SetUp(),
so those tests might've worked just because something else initializes ICU
before it's used in tests (we've got at least one more InitializeICU() method in
v8).

LGTM
